[Bug] Unity on Linux crashes for me with the experimental lightmap baker

Can someone who's on Ubuntu try to reproduce this? I'm running the editor on Manjaro.

When I have a few static objects set up and I switch from the lightmap baker from Enlighten to Progressive in the lighting panel, the editor crashes right afterIt prints this to stdout:

CPU time limit exceeded (core dumped)

Running $ ulimit shows that I have no limits in place on CPU time.

 

I've noted the existence of this bug before: https://forum.unity3d.com/threads/progressive-lightmapper-crash.463862/

So far, no official acknowledgement from anyone.
