GL Teapot Seg Fault with Screensaver Test

Reported by: cebif Owned by: korli
Priority: normal Milestone: R1
Component: Kits/OpenGL Kit Version: R1/pre-alpha1
Keywords: Cc:
Blocked By: Blocking:
Platform: All

Description

If I run GL Teapot and then open Screensaver from Preferences, go to Modules tab and click test, I get a segment violation in GL Teapot. There are two variations in how it appears. Sometimes the whole screen freezes and I cannot clear it by moving the mouse or pressing a key. The keyboard and mouse seems to be working because I can toggle Caps Lock and Num Lock. Ctrl+Alt+Del wont bring up Team Monitor or it is obscured by the frozen screen. The mouse hand becomes visible after pressing Ctrl+Alt+Del, and I can move it around. The screen has part of GL Teapot and everything else looks black. The other variation is when gdb window comes up and I can get a backtrace. This is reproduceable every time with these two variations. The version I was testing is: hrev22114 on it's own partition.

Can't reproduce.

If you cannot reproduce it were you using a later version than hrev22494. I can still reproduce it with this. I don't know if this has any relevance but was it also in a virtual machine that you tried to reproduce it? I will see anyway for myself with a virtual machine with vmware.

korli, I tried with the r22586_vmware and the bug did not show. Next I will try with this same version on its own partition.

korli, I have just tried with hrev22586 on its own partition and cannot reproduce the bug with this version. The bug seems to have been fixed. Is it a side effect of fixing another bug/bugs? I was able to reproduce once something close to the original bug I reported but after many retries and gradually bringing all my own settings cannot reproduce it again.

Resolution: fixed
Status: newclosed

Yes, it was crashing at a time, but not with the yesterday version, both on real hardware and vm. It should be a side effect of some other bug (vm/page daemon). I close the bug. Of course, it can be reopened if a crash happens with the same conditions.
