Short description of error
frequent crashes when switching viewport into "Rendered"

Exact steps for others to reproduce the error
Average scene with heavy OSL materials. Most of the time "Rendered" mode of viewport works well, but sometimes Blender starts to crash when enabling "rendered" in viewport.
In real renders (F12) Blender never crashes, so this is more viewport problem, not OSL itself.
I also noted, that sometime it helps to hide tab with material preview tab (default sphere, etc) - looks like when it updates at the same time as viewport it cause crash.
