Hi,
I installed pthreads-1_60_beta4_1 on SunOS 4.1.3, using gcc2.7.0.
After a stupid trial of passing non allocated pthread_t variable to
pthread_create, I had an infinite loop while running a veray simple
test. Using gdb, it appeard that a segmentation fault occured in
pthread_create() line 193 of the file ./pthreads/pthread.c while
trying to assign the new thread structure to the user one:
193 (*thread) = new_thread;
Wouldn't it be possible to test the assignment of the thread
variable at the very beginning of the pthread_create() function???
e.g.:
140 size_t size;
141
/*
* Testing that the user is not stupid:
*/
if (thread == (pthread_t *) 0) {
/*
* He is:
*/
return !OK;
}
142 if (new_thread = (pthread_t)malloc(sizeof(struct pthread))) {
143
Ok, this is not an issue, but it assumes that the user is intelligent
and will not make something stupid, which is far from being my case;-)
Well thanks for this package, it's great!!!
