System: NetBSD ficus 4.99.72 NetBSD 4.99.72 (FICUS) #11: Sat Sep 13 22:20:01

Machine: i386
>Description:
Simple programs compiled with 'gcc -pthread -pg' dump core.
Same with 'gcc -lpthread -pg'.

The programs fail with the following error detected by libpthread: Invalid
mutex. Detected by file "/usr/src/lib/libpthread/pthread_mutex.c", line 210,
function "pthread__mutex_lock_slow".

#0  0x080554d0 in _lwp_exit ()
#1  0xbbbe5ca1 in pthread_create () from /usr/lib/libpthread.so.0
#2  0x080553f0 in makecontext ()

>How-To-Repeat:
Compile and run the following code with 'gcc -lpthread -pg':

ficus[~] cat test.c
#include <pthread.h>

void *test(void *data)
{
  return NULL;
}

int
main()
{
  pthread_t t;
  pthread_create(&t, NULL, test, NULL);
  pthread_join(t, NULL);
  return 0;
}
