This is not suing SDL2 (AFAICT).

Well:

extern  Bool    XkbSetDetectableAutoRepeat(
        Display *               /* dpy */,
        Bool                    /* detectable */,
        Bool *                  /* supported */
);

and "Bool" is int in X terms - so on sparc64 the last arg ("supported") will
need to be a properly aligned pointer, failure to do that will lead to a
SIGBUS - just like you see it. If you still have the core around, can
you show the output of "bt" in gdb?
