Bug 2430

Summary: Missing initialization of the variable 'centroid' inside SDL_GestureAddTouch
Product: SDL Reporter: klose
Component: *don't know*Assignee: Ryan C. Gordon <icculus>
Status: RESOLVED FIXED QA Contact: Sam Lantinga <slouken>
Severity: normal    
Priority: P2    
Version: 2.0.1   
Hardware: x86_64   
OS: Windows 7   

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));
