<pre>All EGL programs I could find, started to segfault in eglChooseConfig() on all
Intel platforms between following Mesa commits:
* 3de87f7cd7 at 2017-10-17 16:17:15 UTC vulkan/wsi: Free the event in
x11_manage_fifo_queues()
* f37af5ec8d at 2017-10-18 17:36:53 UTC
st/mesa: set dimension for constants in ATI_fragment_shader
There are several commits from Eric that change Mesa EGL code between that
range.
Backtrace to crash is following:
