[Bug 48171] Call of Duty: Modern Warfare (2019) exception

--- Comment #10 from Richard Yao <ryao at gentoo.org> ---
It just hit me after posting my last comment. What is being read is
"${HOME}/.steam/steam/SteamApps/common/Proton
5.0/dist/lib64/wine/fakedlls/gdi32.dll", which is exactly 0x9be0 bytes.
Coincidentally, .init starts right after it. Inside the fakedll, we have a long
section of 3 repeating instructions before any useful code:

    10001a7e:   00 00                   add    %al,(%rax)
    10001a80:   cc                      int3   
    10001a81:   c3                      retq

I am not sure what build of wine Louis Lenders used, but my guess is that it
was proton 5.0 (lucky me). Also, objdump stubbornly displaying addresses like
0x10001a80 on the fakedll, which is consistent with Yurii Kolesnykov's
backtrace.

It looks like the issue involves how the fakedll works. At the very least, the
fakedll seems like the most plausible source of the code being loaded into the
0x11000 sized hole. It certainly is big enough to contain it. This might be a
lead.
