--- Comment #9 from Manuel Moos <[EMAIL PROTECTED]> 2008-12-10 00:53:01 PST --- (Another Armagetron Advanced Developer reporting) We're using custom C++ array classes to feed pointers to OpenGL; they always have a valid data pointer, unlike most STL implementations. Passing NULL pointers into OpenGL is definitely not the problem. I've been using BuGLe to trace our OpenGL usage recently, analyzing the resulting call traces with a small Python program for anomalies; the few (harmless ones; like calling glDeleteLists while recording another list, which should be legal) have been eliminated. glBegin/End pairs definitely match, and all commands inside display lists are legal, no undefined display lists are used. What *may* be the problem is that we're using display list as geometry caches in the new alpha versions (not in previous stable releases, there we only use them for static geometry). We have lots of geometry that is in principle dynamic, but doesn't change often on a frame-to-frame basis; so to optimize rendering, we put it into display lists and only update the lists when something changes. The way we do this can result in *empty* display lists from time to time. Anyway, at least for software rendering, it seems Mesa 7.2 is no longer afffected by this problem: https://bugs.launchpad.net/armagetronad/+bug/245925/comments/10 I'm asking the DRI users to verify this. Assuming 7.2 turns out to be clean for them, too: If you still want us to get down to the root of the issue for 7.0.x and 7.1, I can reproduce the crash there rather reliably now with the debug recording attached to the linked comment. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. ------------------------------------------------------------------------------ SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.
