Bonjour Raffi,

I was able to reproduce the crash with this minimal source:

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

struct f
{

    f()
    {
        boost::unit_test::master_test_suite_t master_test_suite =
            boost::unit_test::framework::master_test_suite(); /* crashes later because of this line */
    }
    ~f() { }
};

BOOST_FIXTURE_TEST_CASE(sample_test, f)
{
    BOOST_TEST(true);
}

I noted the critical line above.

My goal is to access the path of the executable, and that static getter to the master test suite is apparently the right way to get it.

I've been able to bypass the crash by avoiding keeping the ref as a local variable:

    f()
    {
        boost::filesystem::path exe_dir =
            boost::filesystem::system_complete(boost::unit_test::framework::master_test_suite().argv[0])
            .remove_filename();
    }

IMHO it still seems like a bug that a ref returned in the fixture constructor causes a crash later on program termination?

Hope this helps.  Thanks again for your time,

Nathan

causing the crash. Post your code and I'll try to reproduce on my end.
