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()?

The latest development version of SDL is available via Mercurial. Mercurial allows you to get up-to-the-minute fixes and enhancements; as a developer works on a source tree, you can use "hg" to mirror that source tree instead of waiting for an official release. Please look at the Mercurial website ( http://mercurial.selenic.com/ ) for more information on using hg, where you can also download software for Mac OS X, Windows, and Unix systems. hg clone http://hg.libsdl.org/SDL If you are building SDL with an IDE, you will need to copy the file include/SDL_config.h.default to include/SDL_config.h before building. If you are building SDL via configure, you will need to run autogen.sh before running configure. There is a web interface to the subversion repository at: http://hg.libsdl.org/SDL/ There is an RSS feed available at that URL, for those that want to track commits in real time.
