I found out some apps recompiled with KSE libpthread (not from ports, just by
myself from original sources) are terminated with this message while worked
fine for libc_r; here's the source (lib/libpthread/thr_spinlock.c):
void
_spinlock(spinlock_t *lck)
{
struct spinlock_extra *extra;
if (!__isthreaded)
PANIC("Spinlock called when not threaded.");
if (!initialized)
PANIC("Spinlocks not initialized.");
/*
* Try to grab the lock and loop if another thread grabs
* it before we do.
*/
if (lck->fname == NULL)
init_spinlock(lck);
extra = (struct spinlock_extra *)lck->fname;
pthread_mutex_lock(&extra->lock);
}
Removing the 1st check works for most apps, but some of 'em (xmms is the one)
hang up there; can anyone tell me what can be wrong there?
