Dirt 4 crashes after launching" href="https://bugs.freedesktop.org/show_bug.cgi?id=111339">bug 111339</a> from <a class="email" href="mailto:denys.kostin@globallogic.com" title="Denis <denys.kostin@globallogic.com>"> Denis</a> <pre>:( I took my SKL. I was able to reproduce the issue on mesa-master - but, after about 5-10 times (crashing it) - it stopped crashing, and launched normally. Interesting, that even I exchanged mesa libs or not after that, it didn't "load" long time (as you mentioned, first launch with "custom" libs usually tooks about 5-10 minutes). Also I built "debug" mesa, and tried to get gdb backtrace, and it looks not well. @Leozinho, could you please build mesa with gdb symbols and try to read gdb? Below you can find how I built mesa, and my core-dump output: export CFLAGS='-O0 -ggdb3 -g' export CXXFLAGS='-O0 -ggdb3 -g' meson setup . mbuild_dbg_x64 -Dbuildtype=debug --prefix=/home/ubuntu/mesa_versions/mesa-git-15.08 -Dvalgrind=false -Ddri-drivers=i965 -Dgallium-drivers=iris -Dvulkan-drivers=intel -Dgallium-omx="disabled" -Dplatforms=x11,drm,surfaceless -Dtools=intel -Db_ndebug=true ninja -C ./mbuild_dbg_x64/ install coredump: ubuntu@ubuntu:~/mesa$ gdb '/home/ubuntu/.steam/steam/steamapps/common/DiRT 4/bin/Dirt4' '/home/ubuntu/.steam/steam/steamapps/common/DiRT 4/bin/core' GNU gdb (Ubuntu 8.1-0ubuntu3) 8.1.0.20180409-git Copyright (C) 2018 Free Software Foundation, Inc.
