 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

 }}}
 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.
