Note that I don't find it all that useful since it seems to be
compiled without posix thread support. So, in general I compile my own
gcc (or concept-gcc). But I mentioned the cygwin gcc here since it
will make the issue easier to reproduce.

Hearing no reply from the test lib authors, I did a bit more research.
It seems that if I manually register my test cases instead of using
BOOST_AUTO_TEST_CASE the crashes in my tests disappear. From this I
conclude that the issue lies in the additional test case destruction
machinery that comes into play when the macro is used. I am rewriting
my code to avoid the macro now. Though more verbose, debugging is
clearer, the code is more readable, and it doesn't crash anymore. I
would be interested to learn what's going wrong though.
