This is incorrect. It does lock the mutex again.:
(from __pthread_cond_dowait which implemented pthread_cond_wait)
(*themutex)->Lock ();
if (last == true)
(*cond)->mutex = NULL;
if (pthread_mutex_lock (&(*cond)->cond_access))
system_printf ("Failed to lock condition variable access mutex, this
%p", *c
ond);
InterlockedDecrement (&((*themutex)->condwaits));
if (pthread_mutex_unlock (&(*cond)->cond_access))
system_printf ("Failed to unlock condition variable access mutex,
this %p",
*cond);
return rv;
}
Chances are your test app is buggy, or you are making one or more
assumptions about the mutex type (ie recursiveness etc) that are
incorrect.
