And it looks like I do need to include the "-fps" command line parameter to trigger the crash. Created attachment 36422 [details]
Output from valgrind
This looks like the important part:

Another bug in Draw. I've just updated to the following revision: commit 4503bd33dac04bb925780852e49f2ffa501ebc0a Author: Zack Rusin <zackr@vmware.com> Date: Fri Jun 25 20:06:53 2010 -0400 draw: deleted by mistake and this bug is no longer present. (I have no idea which commit has actually fixed it though.) |

Created attachment 36409 [details] Backtrace from endgame crash The OpenGL xscreensaver hack "endgame" crashes almost immediately with Gallium from git. I have a Radeon RV350 running with Fedora 13's Xserver and the xorg-ati-drv from git. The backtrace is attached: it looks like heap corruption.
