Comment 1 Christoph Feck 2019-07-03 11:53:21 UTC 
Crash is in libEGL_mesa.so or i965_dri.so (Mesa/Intel OpenGL driver). Interestingly, i965_dri.so is running in Thread 4 and crashing in Thread 12, so it might be a multithreading issue.

Please report this issue directly to Mesa developers via https://www.mesa3d.org/bugs.html
