--- Comment #4 from Maarten madebr@gmail.com --- I fixed SDL's sdlprocdump minidump generation in https://github.com/libsdl-org/SDL/commit/be43dec79848e5dc16ec0767ee691eb62b0..., but the wine segfault can still happen when passing a NULL ExceptionParam, as explained in https://bugs.winehq.org/show_bug.cgi?id=56932#c3
Feel free to close this issue if you think this was user error, or keep it open when you think this should be fixed in wine.
