Segfault when compiling first run shaders

When I upgraded to 4.10 from 4.9 I found I could no longer start UE4Editor. It gets to 35% and then crashes, seemingly while compiling the basic shaders it needs. 4.9 didn’t have this issue and could be used fine on the same machine/os. I’m running Arch linux on an intel core i5 and unfortunately on the built in HD4000 GPU (I know, I know, but I can’t afford anything better right now, and 4.9 would at least /run/)

When I followed the suggestion to enable some kind of verbose mode on shader compilation I got this interesting error:

I’m going to go back to 4.9 for now, as I’m not sure what to do with this error. Mesa is upgraded to latest, but of course only gives OpenGL 3.3 features on intel. Is it possible that UE4 now /actually/ requires OpenGL 4?
