Subject: New release?
Date: Mon, 07 May 2012 19:02:00 -0000	[thread overview]
Message-ID: <> (raw)


I have encountered a severe bug on a 64-bit MinGW build 
( of version 2.8.0.

pthread_mutex_trylock always returns 0, no matter if the lock is held or 
not, and it never takes the lock. This causes pthread_mutex_destroy to 
always fail, and probably has other bad effects.

To reproduce, try the following.

int res_init = pthread_mutex_init(&mutex, NULL);
int res_lock = pthread_mutex_lock(&mutex);
int res_trylock = pthread_mutex_trylock(&mutex);
int res_trylock2 = pthread_mutex_trylock(&mutex);
int res_unlock = pthread_mutex_unlock(&mutex);
int res_destroy = pthread_mutex_destroy(&mutex);
printf("res_init=%d, res_lock=%d, res_trylock=%d, res_trylock2=%d, 
res_unlock=%d, res_destroy=%d\n", res_init, res_lock, res_trylock, 
res_trylock2, res_unlock, res_destroy);

This seems to have been fixed in the latest cvs release. Since it has 
also been almost 6 years since the last release, could we please get a 
new release soon?

Thank you.
