i had several mozilla crashes lately, besides the notorious "crash after
being paged out"

 assertion "0" failed: file "/cvs/src/lib/libpthread/pthread.c", line
 394, function "pthread__idle"

also two another which happened during page loading

 assertion "target->pt_state !=3D PT_STATE_RUNNING" failed: file
 "/cvs/src/lib/libpthread/pthread_sig.c", line 757, function
 "pthread__kill"

 assertion "PTQ_LAST(&pthread__runqueue, pthread_queue_t) !=3D qhead"
 failed: file "/cvs/src/lib/libpthread/pthread_run.c", line 237, function
 "pthread__sched_bulk"


also with the latest -current update (1.6R, Sat Apr 26 16:46:01 CEST 2003),
ogg123 started crashing on end of the track or forced exit:

 Error detected, file "/cvs/src/lib/libpthread/pthread_mutex.c", line 338,
 function "pthread_mutex_unlock": Unlocking mutex owned by another thread.

and wxGTK applications (e.g., wip/poedit) crash on start (confirmed by jmmv
for different packages) with the same error as ogg123 on exit:
