File Dialog crashes with illegal instruction (MinGW)

[evilnose]

With SDL3 on MinGW, calling SDL_ShowSaveFileDialog and SDL_ShowOpenFileDialog will crash with illegal instruction. The file dialog still appears. This happens on the latest master branch commit, as well as on a random commit a few months ago.

Minimal sample:

inline void noop_callback(void *userdata, const char * const *filelist, int filter) {
}

inline void get_file_path(SDL_Window *window) {
  SDL_ShowSaveFileDialog(noop_callback,
                         nullptr /* userdata */,
                         nullptr /* window */,
                         nullptr /* filter */,
                         0 /* nfilters */,
                         "C:/foo.txt");
}

I've tried providing a window as argument, which oddly causes the file dialog to no longer appear, but the crash still occurs.

What's the call stack?

[evilnose]

@slouken I was linking against the DLL and couldn't obtain the call stack beyond my code using MinGW's gdb. I'm assuming that my CMAKE_BUILD_TYPE=Debug is propagating to SDL, so I'm not sure why this was the case.

So then I changed to static linking -- and the error disappeared! Everything seems to work fine now.
It seems the error might only occur when linking against a DLL on MinGW?

As a side note (I'm a noob on this), can I just get away with static linking SDL? I don't think executable size is a concern, since I think I'll need to distribute the DLL with my app even if I used dynamic linking. Would there be any other possible concerns?

[evilnose]

Actually, I just rebuilt the project with dynamic linkage again and things are working fine now.
I've done a clean build before and the error was still there; but this time it's somehow disappeared.
I'll try some other arguments and see if I can repro this error again.
