Many core dumps in pthread_getspecific.

Hi,
I'm new to FreeBSD and I'm running into a lot of core dumps (mainly from Xorg, but also from vim, firefox, ...).
That's why I asked on freebsd-questions:

The last Xorg crash was less than 2h ago. :(
It looks like that there is a missing check for NULL in lib/libkse/thread/thr_spec.c (line 211-214):
pthread = _get_curthread();
/* Check if there is specific data: */
if (pthread->specific != NULL && (unsigned int)key < PTHREAD_KEYS_MAX) {
If pthread is NULL it will core dump. So maybe something like this would help:
if (pthread != NULL && pthread->specific != NULL && (unsigned int)key < PTHREAD_KEYS_MAX) {
But as I'm said, I'm new to FreeBSD I can't evaluate it yet.
I'm running the most recent stable:
% uname -a
FreeBSD andre 10.1-RELEASE-p10 FreeBSD 10.1-RELEASE-p10 #0: Wed May 13 06:54:13 UTC 2015
I haven't compiled the base system so far. Maybe a more experienced FreeBSD guy can verify this and decide if it makes any sense or if I have to dig any deeper into it.
Sincerely yours Andre.
