Description David 2012-12-07 08:44:58 UTC 
Hello,

Using Mesa 8.0.4 from Debian Wheezy / Testing.  Sometimes (maybe 1 in 5 times) while changing resolutions, I get a crash in supertuxkart.

I filed a bug against supertuxkart and they think it is a bug in the graphics driver.

Thanks for your time.

Here is the dbg output:

Comment 1 David 2012-12-07 09:23:06 UTC 
The gdb output from using upstream's binaries of the game is a little bit different, but it still crashes and it looks like it's inside of r300_dri.so.

Running supertuxkart in valgrind might yield more information about the double free or memory corruption.

First run of Valgrind, it looks like Valgrind crashed with the app?

Second run of Valgrind, it didn't crash.
Comment 5 Michel Dänzer 2012-12-07 15:47:35 UTC 
According to the valgrind output, the supertuxkart / irrlicht code is writing to some memory after freeing it, which could explain the problem. I think you should take this back up with the supertuxkart developers. Feel free to reopen if the problem persists after fixing those invalid writes.
