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/snakeqr/

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.
