If this hasn’t been caught yet, there’s an improper method of calling a
user’s window
message routine in the various SDL_xxevents.c files.
For example, in SDL_dx5events.c, at the end of the function
DX5_HandleMessage(),
there’s a call like this:
} else if (userWindowProc) {
return userWindowProc(hwnd, msg, wParam, lParam);
}
which should be:
} else if (userWindowProc) {
return
CallWindowProc(userWindowProc,hwnd,msg,wParam,lParam);
}
Calling it improperly can cause a crash under at least XP.
S.W.
