Comment 2 Steven Morgan 2015-04-29 17:11:17 EDT 
Looking into this - it works OK on my Mac OS X x64, but it is a little behind what you are running(Darwin Kernel Version 13.4.0 vs Darwin Kernel Version 14.3.0). Are you using any parameters on ./configure?
Comment 3 Daniel J. Luke 2015-04-29 17:33:35 EDT 
yep, this is actually built with the MacPorts port (which I maintain). Mac OS X 10.10.3 .

Configure is run with:

./configure --prefix=/opt/local --mandir=/opt/local/share/man --with-zlib=/opt/local --with-openssl=/opt/local --disable-silent-rules

the MacPorts provided zlib is version 1.2.8 and openssl is 1.0.2a
Comment 4 Daniel J. Luke 2015-04-29 17:40:40 EDT 
libclamav/c++/configure has the problem from #11188, which is probably causing this. I'm patching/rebuilding now to test.
Comment 5 Daniel J. Luke 2015-04-29 17:56:57 EDT 
looks like patching libclamav/c++/configure did not fix this - I'm still seeing the same crash.
Comment 6 Daniel J. Luke 2015-04-29 17:58:52 EDT 
I should be running the latest Xcode/command line tools too:

% clang --version
Apple LLVM version 6.1.0 (clang-602.0.49) (based on LLVM 3.6.0svn)
Target: x86_64-apple-darwin14.3.0
Thread model: posix
Comment 7 Steven Morgan 2015-04-29 18:24:44 EDT 
Mine is slightly behind again:

Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 6.0 (clang-600.0.57) (based on LLVM 3.5svn)
Target: x86_64-apple-darwin13.4.0
Thread model: posix

Can't see any recent code changes affecting this...

Your same setup is working with ClamAV 0.98.6?
Comment 8 Daniel J. Luke 2015-04-29 18:26:01 EDT 
yep - although I believe my 0.98.6 was built on whatever OS & Xcode release was current when it was released.
Comment 9 Daniel J. Luke 2015-04-29 20:32:31 EDT 
Created attachment 6872 [details]
some more crash info (from lldb)

this may or may not be helpful but I rebuilt with --enable-debug and did 'frame variable' for each frame that had info.
Comment 10 Daniel J. Luke 2015-04-29 20:43:26 EDT 
As as stupid hack, if I comment out the body of the destructor in clamav-0.98.7/libclamav/c++/llvm/lib/CodeGen/MachineSSAUpdater.cpp (the delete &getAvailableVals(AV);), it runs without crashing.

You could also try using ./configure --enable-llvm=no or --with-system-llvm options as possible workarounds.

I don't think Apple ships an llvm-config for the configure script to find (I could pull in a MacPorts provided llvm, I guess). I would imagine it would work with --enable-llvm=no.

and I can confirm that this does work. I'll re-enable it in the MacPorts port once this bug has a fix.
Comment 14 Larry Stone 2015-04-30 12:43:04 EDT 
An additional symptom of (apparently) this bug: Clamd gives a "Segmentation Fault: 11" when trying to run on OS X 10.10.3 after build with default configure/make (also happens with 0.98.6 when built on 10.10.3; 0.98.6 had built fine on 10.9.x with default configure/make). Configuring with --enable-llvm=no works for this symptom as well.

Possibly related: Web searches indicate a number of programs that use libtool are having an issue with 10.10.x due to a test of MACOSX_DEPLOYMENT_TARGET treating 10.10 as if it's 10.1.

that's bug 11188 - after patching libclamav/c++ configure (and verifying that the top-level configure is already patched), the crash still happens.

I get "You are not authorized to access bug #11188."
Comment 17 Mark Allan 2015-04-30 14:11:21 EDT 
Will compiling with --enable-llvm=no mean that there will be no support for bytecode signatures?

If so, is the advice for package maintainers to stick with 0.98.6 or compile with llvm=no while we wait for 0.98.8? Which is the lesser of two evils and will 0.98.8 be release soon as a quick fix?

--enable-llvm=no disables use of the llvm just-in-time compiler for ClamAV bytecode signatures. In this case, the built-in ClamAV bytecode interpreter handles ClamAV bytecode signatures.

I would go with 0.98.7 if possible.

Yep. Now that I can see 11188, I can say I had already tried patching those two files based on what I was reading elsewhere and still got the segmentation fault so will conclude that my issue with clamd is unrelated to the libtool MACOSX_DEPLOYMENT_TARGET issue.

Comment 21 Steven Morgan 2015-05-28 10:58:33 EDT 
Additional note: we need to make sure that the unit tests (make check) work on Mac OS X 10.10.3. This issue was reported in bug #11324. It appears to be the same underlying cause (llvm).
Comment 22 Sierk Bornemann 2015-09-13 08:06:30 EDT

(In reply to Sierk Bornemann from comment #22)
> Any progress in this issue?

It appears to be an issue compiling the built-in LLVM JIT using -O2. These are the possible work arounds identified so far:

- compile llvm unoptimized: ./configure CXXFLAGS='-O0'
- use llvm library already your system: ./configure --with-system-llvm
- use the bytecode interpreter instead of LLVM JIT: ./configure --enable-llvm=no
Comment 24 Eiichi Yokota 2015-10-21 04:57:20 EDT 
ClamAV 0.98.7 and ClamAV 0.99.0-rc1 built on OS X 10.10 Yosemite and on 10.11 El Capitan have this issue.

ClamAV 0.98.7 and ClamAV 0.99.0-rc1 built on OS X 10.9 Mavericks has no issue.
Comment 25 Eiichi Yokota 2015-10-22 23:43:36 EDT 
I tested to build and run ClamAV 0.99-rc1 on OS X 10.11.1 (15B42) El Capitan.

1. Versions of LLVM beyond 3.5 seem not be currently supported in ClamAV, so I installed LLVM 3.5.2 to /usr/local.
2. I configured ClamAV to use LLVM that I installed as a system library instead of the built-in LLVM JIT as following:
	---
	export CFLAGS="-O3 -march=nocona"
	export CXXFLAGS="-O3 -march=nocona"
	export CPPFLAGS="-I/usr/local/ssl/include"
	./configure --prefix=/usr/local/clamXav --build=x86_64-apple-darwin`uname -r` --with-openssl=/usr/local/ssl --with-pcre=/usr/local --with-system-llvm=/usr/local/clang+llvm-3.5.2-x86_64-apple-darwin/bin/llvm-config
3. Now now clamd and freshclam are running steadily as daemon.

Correct, some interfaces to LLVM have changed in 3.6/3.7. Work is in progress to get those versions supported by ClamAV --with-system-llvm. I've just added some info to docs/clamdoc* about LLVM support.

Is there a recommendation for which option packagers should be using (MacPorts is using the third option currently, but I can easily switch it to something else).

I personally favor the 3rd option, followed by the 2nd, and lastly the 1st. Here are the considerations:

Much smaller ClamAV code footprint for 2nd and 3rd options.

Slightly faster in overall execution time with JIT (~.5% in our overall system measurements). Although, JIT can be much faster(~5X) when measuring long-running bytecode signatures and viewing only the bytecode signature execution time (measured with clamscan --statistics=bytecode). We don't ship that many bytecode sigs, which may partially explain the negligible overall difference. Also, of these, only one or two tend to be long-running.

If using option two, you can get a more llvm version than than the built-in llvm, for whatever that's worth.

What about using the --with-system-llvm option

--with-openssl=/opt/local \
--with-pcre=/opt/local \
--with-system-llvm=/opt/local/libexec/llvm-3.5/bin/llvm-config

on MacPorts' port file, creating a dependence on opensssl, pcre llvm-3.5 (or greater) ports?

I use that for my ClamXav BYO, and it seems to work very well (I've installed pcre, openssl, llvm-3.5 via MacPorts).

[snip]

If you'd like to have a MacPorts discussion, we should probably do it outside of the clamav bugtracker (feel free to post to the macports mailing lists, though). I'm hesitant to add a dependency on llvm-3.5 since it's a pretty large/long build.

Just for reference.
 
Now versions of LLVM beyond 3.6 seem to be supported in ClamAV 0.99.1.
I installed LLVM 3.6.2 to /usr/local and build ClamAV 0.99.1 using
--with-system-llvm=/usr/local/clang+llvm-3.6.2-x86_64-apple-darwin/bin/llvm-config

I can succeed to build and run ClamAV 0.99.1 on OS X 10.10 Yosemite and on 10.11 El Capitan.

I can confirm that for LLVM 3.6.2, it seems to build and work fine.

For LLVM > 3.6: the build fails for LLVM 3.7.1 with --with-system-llvm=/opt/local/libexec/llvm-3.7/bin/llvm-config and the build process breaks shortly after:

[..]
configure: Using external LLVM
checking for supported LLVM version... no (3.7.1)
configure: error: LLVM < 3.7 required, but "3.7.1"(371) found
configure: error: Failed to configure LLVM, and LLVM was explicitly requested
[..]

I've not tested with upcoming LLVM 3.8 release (on SVN server already tagged and branched as "final release") or LLVM 3.9svn trunk.
