#4949 closed bug (fixed)

Beam threads crash on exit in some pthread cleanup methods

It looks like this has been caused by making every thread convertible into a pthread recently.

The crash is a segment violation. I am running hrev34023.

Can you try to replace malloc with malloc_debug? It crashes in a libbind destructor function.

I downgraded to hrev33966, too many issues with the bleeding edge. :-) I did see Firefox threads crash with a very similar stack trace, if that helps. Are the global destructors keyed to pthread exit hooks even supposed to be called for regular threads? Maybe something is deleted twice now because of this?

Besides the crash, it's supposed to work like this. And I'm running the "bleeding edge", too, without any such issues.

I guess I can try to upgrade and report my findings with malloc_debug. (Is the shell tab completion working again in trunk?) I find it strange that both Beam and Firefox start crashing for me like this after that change and work 100% reliable on hrev33966. Are you sure you don't have any uncommitted changes? ;-)
