Description Alex Villacís Lasso 2008-11-27 08:54:46 UTC

Linux 2.6.26.6-49.fc8 Fedora 8

All code checked out as of 2008/11/26 17:00 GMT -5

Compile went OK and non-compositing environment (WindowMaker) appears to work OK. But starting compiz causes a server crash and leaves the screen in graphics mode. 

This is the same system as bug #17723, but it is NOT a duplicate of it. Previous build of xserver git tree worked Ok with 64 MB ram. Current build crashes on same conditions.

dmesg output right after crash

System is still responsive, and can be ssh'd into. That is how I got these files. ps aux shows no trace of the xserver process, so it has crashed, but I see no trace at all on the log file.

Comment 4 Michel Dänzer 2008-11-27 09:30:59 UTC

The key line is

X: shader/prog_statevars.c:783: append_token: Assertion `0' failed.

Looks like the failing assertion was introduced in mesa commit 11701b4c151de450e0b80d9e61266ff178b4bd60 ('mesa: add some missing switch cases for generating state var strings').

Comment 5 Brian Paul 2008-11-27 10:02:08 UTC

I'm removing the assertion.  It's harmless.  But it would be nice to know what the switch value is that's not handled.

Comment 6 Alex Villacís Lasso 2008-11-27 11:30:02 UTC

I commented out the assertion and put in its place a call to _mesa_problem. I get the following:

Mesa 7.3-devel implementation error: unhandled state index 0x0000009e while appe
nding to 'state.(internal)'

Please report at bugzilla.freedesktop.org

...but otherwise the problem is 'fixed'.

Console output with assertion commented out and replaced with message

Comment 8 Brian Paul 2008-11-28 12:51:38 UTC

OK, 0x0000009e corresponds to driver-private state.  I'm committing a minor change/fix.  Closing this bug.
