Call to SDL_Init crashes process with AccessViolation when gamecube controller and mayflash adapter attached

[Chicken-Bones]

Game: tModLoader
OS: Windows 10 Home X64 (19044.1586)
Runtime: NetCore 6.0.3

Crashes both with VS attached and when launched from a system or portable dotnet install. Commit 81148b7

Official gamecube controller with https://www.mayflash.com/product/showproduct.php?id=27
No crash when using a generic third party adapter (looks like but might not exactly be https://www.amazon.com/Switch-Gamecube-Controller-Adapter-Nintendo/dp/B07Q459FBQ)

A breakpoint set on the line after SDL_Init never gets hit. Removing SDL_INIT_HAPTIC lets it get further, but it appears to make the process unstable and it crashes not much later.

Log from init with adapter which does work

Looking through the diff between our version and the latest, I should try with 921bdb5

You're probably looking at something in SDL instead - the SDL VisualC folder includes some controller tests, try those and file a report here: https://github.com/libsdl-org/SDL/issues

Update, with 089197a it crashes at SDL.SDL_GameControllerOpen(dev);

Probably won't have time to try and run SDL tests unless I can get a binary from someone, so I'll just leave it here as a reference open issue for anyone in the future.

Here is the sln you want: https://github.com/libsdl-org/SDL/tree/main/VisualC

It depends on nothing other than Win32 (it doesn't even require msvcrt), so if you have some kind of VS you'll be able to build everything in a few seconds (even with modern Visual Studio).
