The issue does not happen in recent mesa sources, but apparently the code path
leading to the crash is in all rhel9 packages.

While dri_put_drawable checks for a NULL pointer:
/usr/src/debug/mesa-22.1.5-2.el9.x86_64/redhat-linux-build/../src/gallium/frontends/dri/dri_util.c:
648 static void dri_put_drawable(__DRIdrawable *pdp)
649 {
650 if (pdp) {
651 pdp->refcount--;
652 if (pdp->refcount)
653 return;
...
this code path dereferences a NULL pointer:
695 static void
696 driDestroyDrawable(__DRIdrawable *pdp)
...
705 */
706 pdp->loaderPrivate = NULL;
707
708 dri_put_drawable(pdp);
Regardless of it being caused by some kind of misconfiguration, this segfault
should not happen.
