Fixed bug #1056 (Frequent crashes in Touch events by simply touching the screen)
Joseba García Echebarria 2010-12-15 01:55:22 PST
I believe the crash is caused by a check not being performed on wether an
SDL_Touch element is NULL before using it in the SDL_SendTouchMotion function
in src/events/SDL_touch.c around line 400.
Judging from the rest of the code, there's a missing
if (!touch) {
return 0;
}
before using "touch" as SDL_GetFinger(), SDL_GetFingerIndexId() use
touch->num_fingers without checking.
I can attach a patch if you like. It seems pretty straightforward, though.
I have yet to discover why touch is being returned as NULL as this error is
only triggered when an actual gesture has been performed, maybe something
related to SDL_AddTouch()?
