Summary: Regression: Half Life 2 random crashes since 56e95d3c
Severity: normal
Classification: Unclassified
OS: All
Reporter: stefandoesin...@gmx.at
Hardware: Other
Status: NEW
Version: git
Component: Mesa core
Product: Mesa
Half Life 2 running in Wine crashes randomly on r300g. This is a regression. A
bisect found this patch:
56e95d3ca231110188e5b910f4e17104f3176d52 is the first bad commit

mesa: validate that sync objects were created by mesa
Previously, the user could send in a pointer that was not created
by mesa. When we dereferenced that pointer, there would be an
exception.
Now we keep a set of pointers and verify that the pointer
exists in that set before dereferencing it.
Note: This fixes several crashing gles3conform tests.

Thanks to Steam's crash handler it is tricky to get a backtrace. I managed to
get some backtraces with function names but without source code references, and
it appears that the crashes occur in various functions deleting GL objects -
ARB shaders, VBOs, textures, maybe others.
Half Life 2 also crashes on r600g, but I have not yet checked if it is caused
by the same patch.
