This code has changed a lot since 6.5.2. Could you possibly try the latest code from git? It took me some time to manage to build Mesa git (probably because the build system has changed since 6.5.2, making the Debian packaging fail to build). But, now it seems that trackballs works fine, or at least does not crash anymore when starting a new game. Just to be sure of what I tested, on a x86 machine with a i945 chipset: * I built Mesa with linux-dri-x86 * I installed the new libGL.so.1.2 and i915_dri.so * I started the game and saw the new libGL.so.1.2 and i915_dri.so appear in /proc/<pid>/maps If it looks fine, I guess the bug is fixed in current git. Brice OK. Closing. |

This bug has been reported on the Debian BTS 2 months ago by Michael Musenbrock. It is easy to reproduce with 6.5.2 (and Xserver 1.3-rc3). Just start the game (trackballs) and press "new game" and then "start game". I got the following backtrace with mesa 6.5.2: $ gdb trackballs GNU gdb 6.4.90-debian Copyright (C) 2006 Free Software Foundation, Inc.
