--- Comment #5 from William Pierce <wgpierce17 at gmail dot com> ---
I think the repro crash in DXVK could be perturbed in a few different ways, and
my previous comment was running into a few different ways it could be
perturbed. The crash also doesn't repro if I run ld under valgrind while
building. Though for a memory corruption, these could make sense.
Nick, your patch completely fixes the problem for me.
I tested the patch being very careful to not perturb the setup in wrong way as
I had seen. I very clearly saw the crash repro without your patch applied and
not repro with it applied.
I also tried out the build running with ld under valgrind with and without your
patch. Without your patch, there are many errors (but, somehow I don't observe
the crash when running the built dll as I mentioned). With your patch, there
are no errors at all (and the built dll runs fine).
Building DXVK with mingw-w64-binutils as mentioned before is sufficient to see
the memory corruption errors with ld during build time. I don't yet have an
easy example app to demonstrate the crash when using the built dll. Bayonetta
on Steam was being used for testing in the DXVK bug
https://github.com/doitsujin/dxvk/issues/1625, but the crash happens for a
variety of D3D applications.
Thanks a ton for the fast response!
