Linux - Crash when moving/turning the viewport camera in project that contains hair

Linux - Crash when moving/turning the viewport camera in project that contains hair

Description

I've attached the project log, crashreport, and crash info to this ticket. This issue only appears to be happening on Linux (On both Nvidia/AMD cards) and does not happen when the hair is disabled in the project.

Steps to Reproduce
  1. Download and open the repro project
  2. Move and turn around in the viewport for a few seconds

Result: Project crashes

Expected: Project does not crash, viewport moves around as normal
