Tracking Issue: Remaining Windows problems from `boguex`

[jonahbeckford]

This is a FYI. I won't be getting to these soon but I wanted to track them somewhere.

• Getting random segfaults. Likely there is memory corruption somewhere.
• Playing sound (examples 36 and 37) works but they hang when they are done.
• Getting warnings on startup because which is not a Windows program:

  Loading Bogue 20240127 with config dir Y:/source/dksdk-coder/.ci/o/dkml/share/bogue/themes\default
  'which' is not recognized as an internal or external command,
  operable program or batch file.

  INFO: Using SDL 2.30.0
  

Setup:

• Source: Latest code with newly created PRs for tsdl and dune
• Build: dune build -p bogue '@install' and dune install
• Run: cmake.exe -E env BOGUE_DIR=Y:/source/dksdk-coder/.ci/o/dkml/share/bogue/themes Y:\source\dksdk-coder\.ci\o\dkml\bin\boguex.exe

I'd be glad to have more info about the segfaults. In my experience, memory leaks could happen when you close SDL Video driver and reopen it again in the same session.( this happens when you run several examples in one boguex run. ) I'm not sure which one of SDL, tsdl, or Bogue should be incrminated. But I don't think I ever got such a problem with a single SDL init

The source code for SDL2 corresponds to https://github.com/libsdl-org/SDL/tree/release-2.30.0 and the line numbers are quite close (but not exact).

For example, the SDL2d!close_audio_device+0x88 [Y:\source\dksdk-coder\vcpkg\buildtrees\sdl2\src\ase-2.30.0-3ceee4a14f.clean\src\audio\SDL_audio.c @ 1208] is https://github.com/libsdl-org/SDL/blob/859844eae358447be8d66e6da59b6fb3df0ed778/src/audio/SDL_audio.c#L1206
