Bug 2953

Summary: Crash due to a bad cleanup in the SDL_SYS_HapticQuit function
Product: SDL Reporter: Mathieu Laurendeau <mat.lau>
Component: hapticAssignee: Sam Lantinga <slouken>
Status: RESOLVED FIXED QA Contact: Sam Lantinga <slouken>
Severity: normal    
Priority: P2 CC: philipp.wiesemann
Version: 2.0.3   
Hardware: All   
OS: Windows (All)   

Description Mathieu Laurendeau 2015-04-21 07:27:16 UTC 
I think the following lines are missing at the end of the SDL_SYS_HapticQuit function:

numhaptics = 0;
SDL_hapticlist = NULL;
SDL_hapticlist_tail = NULL;

This can result in a use-after-free causing a segmentation fault in the DirectInputHaptic_MaybeAddDevice function in case the Haptic subsystem is reinitialized.
