SubjectRe: Possible bug; latest kernels with LinuxThreads

In that case a look at the code always helps :


int __pthread_create_2_1(pthread_t *thread, const pthread_attr_t *attr,
void * (*start_routine)(void *), void *arg)
{
pthread_descr self = thread_self();
struct pthread_request request;
if (__pthread_manager_request < 0) {
if (__pthread_initialize_manager() < 0) return EAGAIN;
}
request.req_thread = self;
request.req_kind = REQ_CREATE;
request.req_args.create.attr = attr;
request.req_args.create.fn = start_routine;
request.req_args.create.arg = arg;
sigprocmask(SIG_SETMASK, (const sigset_t *) NULL,
&request.req_args.create.mask);
__libc_write(__pthread_manager_request, (char *) &request,
sizeof(request));
suspend(self);
if (THREAD_GETMEM(self, p_retcode) == 0)

>>>> *thread = (pthread_t) THREAD_GETMEM(self, p_retval);

return THREAD_GETMEM(self, p_retcode);
}

The line marked >>>> is line 488 in pthread.c , are you plain sure that
you're not passing a NULL thread id ptr ?
