Any news? Quite a frequent crash, when OSL used heavily ///

Not sure if this might help, but I'm seeing the same bug in the daily builds of 2.79, while official 2.79b works fine. To my knowledge the only code shared between 2.79 builds and 2.80 beta are the updates to Cycles, so hopefully that narrows down the source of the problem? May be in the newer Cycles/viewport-render code and not the handling of OSL shaders or materials UI display?

I have the theory that it's about the material icons since this same problem happen in the select material drop down menu in Shader Editor. But of course i can be wrong about it.
