Bug ID: 103358
Summary: All EGL programs segfault (regression)
Product: Mesa
Version: git
Hardware: x86-64 (AMD64)
OS: All
Status: NEW
Severity: critical
Priority: high
Component: EGL
Assignee: mesa-dev@lists.freedesktop.org
Reporter: eero.t.tammi...@intel.com
QA Contact: mesa-dev@lists.freedesktop.org
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:
----------------------------------------
$ gdb glmark2-es2

----------------------------------------
-> eglChooseConfig() code calls a NULL pointer.
