Ok, are you sure that the string you passed to pthread_set_name_np could
not have been overwritten in the mean time? For instance by passing to
the thread an argument which resides on the caller stack. Like for instance:
void *thread(void *cookie)
{
pthread_set_name_np(pthread_self(), (char *)cookie);
/* ... */
}
void create_thread(void)
{
char name[]= "name";
pthread_t tid;
pthread_create(&tid, NULL, thread, name);
}
int main(void)
{
create_thread();
/* ... */
}
