I was trying to a run a snake game for Windows that can fit into a QR code:

https://www.mattkc.com/etc/snakeqr/
https://web.archive.org/web/20220616183735/https://www.mattkc.com/etc/snakeq...

The binary was created using the compressing linker Crinkler
(https://github.com/runestubbe/Crinkler)

Convert QR code to exe:
zbarimg -S binary code.png > snake.exe

I encountered the following crash:

wine: Unhandled page fault on write access to 00000024 at address 7BC4AD36
(thread 016c), starting debugger...
Unhandled exception: page fault on write access to 0x00000024 in 32-bit code
(0x7bc4ad36).

ntdll (0x1f92ea38)
  1 0x00420640 in snake (+0x20640) (0x1f92eae8)

Running snake.exe with WINEDEBUG=+relay took forever and didn't seem to contain
any additional information.

--- Comment #3 from Bernhard Übelacker  ---
It looks like doing the link step with Crinkler adds
a custom dll loader to the executable.
That loader seems to try to lookup ntdll.NtdllDefWindowProc_A but cannot
find it and erroneously takes the first export of ntdll, which is A_SHAFinal.

Therefore A_SHAFinal gets called later with wrong parameter and
therefore crashes.

This can be seen by adding this stub entry to dlls/ntdll/ntdll.spec:
+@ stub NtdllDefWindowProc_A

Then the output of snake.exe changes to:
wine: Call from 7BC243E0 to unimplemented function
ntdll.dll.NtdllDefWindowProc_A, aborting

Unfortunately I have currently no Idea how either forwarding this call
from ntdll to user32 can/should work.

Patch adding NtdllDefWindowProc_A

I tried to forward NtdllDefWindowProc_A to DefWindowProcA. I probably added it
to the wrong source file, but the code compiles. However, it still results in
an unhandled exception:

You're right, using the regular MSVC linker results in a binary which works
just fine using wine-8.6 (Staging).

Meanwhile, the snakeqr code has been released under MIT license here:
https://www.mattkc.com/etc/snakeqr/

Based on MattKC's video, I was able to build it myself.

I've been trying to link it with Crinkler 2.2 (cf. the Github repo), but so far
without success.

The video shows output of Crinkler at
https://www.youtube.com/watch?v=ExwqNreocpg&t=748s

One has to jump frame by frame to see it.

3 function calls are being forwarded:

: warning LNK: Entry point not at start of section, jump necessary
Forced alignment of 1 code hunk to 1 (including entry point).

: warning LNK: Import 'HeapAlloc' from 'kernel32' uses forwarded RVA. Replaced
by 'RtlAllocateHeap' from 'ntdll'

: warning LNK: Import 'DefWindowProcA' from 'user32' uses forwarded RVA.
Replaced by 'NtdllDefWindowProc_A' from 'ntdll'

: warning LNK: Import 'rand' from 'api-ms-win-crt-utility-l1-1-0' uses

hack

This hack is utterly wrong but it allows the game to start and play and might
be useful to test other apps that suffer from this bug. It's copy/paste code to
try to load DefWindowProc from user32.dll

There's a test in user32/tests/class.c that shows that it should really be the
other way around: DefWindowProc is forwarded to NtdllDefWindowProc from Vista+
on. That looks like quite a massive change but probably the way to go if one
wants to resolve this bug :(
