Hi,
I've been continuing to work on this, and even with MALLOC_CHECK defined as
2 (which should cause the app to immediately abort when there is a memory
problem), I'm still seeing the same crash where pTh raises abort because it
doesn't think there are any threads left to schedule.
Why else could this be happening? It doesn't seem to be a memory problem
(else MALLOC_CHECK should have aborted the app sooner), and there are
plenty of threads that could be scheduled.
Thanks in advance
Brent
