I also see: Assertion failed: (pthread_mutex_destroy (&m[i]) == 0), function mutex_prioinherit_test, file mutex_d.c, line 1425. and Fatal error 'Thread has returned from _thread_switch' at line 1150 in file /freefall/d/home/deischen/current/src/lib/libpthread/thread/thr_kern.c (errno = 0) I also think I killed pluto1 again (just by running mutex_d). -- Dan Eischen
