RE: [microblaze-uclinux] pthread_mutex_unlock() on unlocked mutex lock system hard

["Zambrano, Keith I\(GE Infrastructure\)" <Keith.Zambrano@xxxxxx>]

Hi,
	I have been evaluating pthreads for a while, I have found that using sleeps in the thread locks up the target board.

Regards,

Subject: [microblaze-uclinux] pthread_mutex_unlock() on unlocked mutex
lock system hard


Hi,

attached code locks system hard.  I'm not sure where to look
for. armnommu works just fine with same code, so this problem should
be microblaze specific. (or SUZAKU specific, I don't know)

does anyone see this?

regards,

#include <stdio.h>
#include <unistd.h>
#include <pthread.h>

pthread_mutex_t mutex = PTHREAD_MUTEX_INITIALIZER;

void thread_func(void *Param){
        int ret;

        printf("process wait\n");
        sleep(1);
        ret = pthread_mutex_unlock(&mutex);
        printf("process run %d\n", ret);

}

int main(void){
        pthread_t thread;
        pthread_create(&thread, NULL, (void *)thread_func, NULL);
        pthread_join(thread, NULL);
        return 0;
}
