Boost.Test segmentation fault when built with clang on Mac OS X.

[manphiz@…]

Mac OS X 10.8.2, Xcode 4.5.1

$ clang -v Apple clang version 4.1 (tags/Apple/clang-421.11.65) (based on LLVM 3.1svn) Target: x86_64-apple-darwin12.2.0 Thread model: posix

Boost is built with clang without -std=c++11.

The problem is shown below:

$ cat boost_test_segfault.cc 
#define BOOST_TEST_MODULE test

#include <boost/test/included/unit_test.hpp>

BOOST_AUTO_TEST_CASE( test1 )
{
    BOOST_CHECK(true);
}
$ clang++ -g -Wall -I/opt/homebrew/include boost_test_segfault.cc -L/opt/homebrew/lib -lboost_unit_test_framework-mt

A detailed gdb session with "bt full" is attached.

Also, on a relevant post on stackoverflow (​http://stackoverflow.com/questions/12695625/boost-test-crashes-on-exit-with-clang-4-1-llvm-3-1svn) the user tried with building boost using clang with -std=c++11 -stdlib=libc++ and compile the test code with the same flag and the executable doesn't crash anymore. But I haven't tested that. I also tried to build the test program with llvm g++, but it runs with the same error.

After some testings, it looks like all compilers on Mac OS X (apple-gcc 4.2.1, llvm-gcc 4.2.1, clang 4.1) are affected.

OK, it seems that I'm not using it right. It seems that at least on Mac OS X one should just use dynamic library or single header, but not both at the same time. Using each flavor the test program runs just fine. So please feel free to close this ticket.
