Hello BDW-GC maintainers,

In file win32_threads.c there is a special case for the static allocation
of the first GC_thread structure.

If someone calls GC_unregister_my_thread() on that very first GC thread
there will be a segmentation violation inside GC_delete_thread() when
it tries to call GC_INTERNAL_FREE().

I attached to this message a patch against 7.2alpha4 that seems to fix the problem.

Cheers,

Jean-Claude Beaudoin
