Ryan Neph requested to merge ryanneph/virglrenderer:rn-glsl-query-error into main Oct 17, 2023

Occasionally (on Intel GLK Chromebooks) we see crashes due to SEGFAULT'd
reads in in sscanf during glsl version querying. These are quite rare,
but with a consistent rate across ChromeOS releases.

This change changes the crash into a fatal runtime error, while the root
cause is investigated.
