Description klose 2014-03-06 08:49:52 UTC 
File: SDL_gesture.c
Method: SDL_GestureAddTouch

When a new SDL_GestureTouch element is added to the global SDL_gestureTouch array the variable 'centroid' of the new element is not initialized.

The problem is that this variable is read isndie SDL_GestureProcessEvent when a SDL_FINGERDOWN event occurs.

Fixed it by adding the following line to the SDL_GestureAddTouch method at the line 422: SDL_memset(gestureTouch, 0, sizeof(SDL_GestureTouch));
