[Bug nptl/11331] New: pthread_cancel() segfaults with an uninitialized thread descriptor

["aurelien at aurel32 dot net" <sourceware-bugzilla at sourceware dot org>]

The following code, though it is clearly invalid, segfaults instead of failing
with -ESRCH. The GLIBC tries to detect invalid thread descriptors, but fails to
catch the uninitialized case. Other libc (e.g. BSD) are able to handle that.

#include <pthread.h>

static pthread_t p;

int main(void)
{
        pthread_cancel(p);
}
