And the bug does not appear with the ATI driver. As discussed in the Debian bug, it seems to be fixed with a recent git. |

This bug has been reported by Joey Hess to the Debian BTS a couple days ago. It is very easy to reproduce, at least on his i915 board and on my i945. When depth is set to 16bpp, starting blobwars immediately segfault the server. It works fine in 8bpp and 24bpp. We have been unable to get any backtrace so far. I rebuilt the whole 1.3.0.0 server and 2.0.0 with debugging enabled and optimization disabled, I always get a corrupted backtrace, either by attaching a gdb, or by running gdb on the coredump later. An (interesting?) note: * the crash does NOT occur when starting the game with startx /usr/games/blobwars * the crash does NOT occur either when starting the server with startx /usr/bin/xterm and then starting blobwars from the xterm * but when starting twm from the terminal and then starting blobwars, the server always crashes I am sorry I can't get a backtrace, but I hope somebody will have an idea to debug this. Thanks, Brice
