My experience with Boehm GC was that it was (apparently) incompatible
with gdb. It always sent segfaulted right away in GC_find_limit. I
thought it was something funky about the app I was debugging, but maybe
not. Your comment sent me to google on 'gdb GC_find_limit' and it seems
that this behavior is normal, and not fatal:
