+( Mesa 7.6 implementation error: bad datatype in interpolate_int_colors Please report at bugzilla.freedesktop.org )+ These two messages have repeatedly filled up /var/log/gdm/:0.log, consuming all of the space on my root partition. The voronoi screensaver was running at the time. I was able to reproduce the problem twice, after a few minutes, by running voronoi in preview mode. I'm running OpenSuSE 11.2, 2.6.31.14-0.6, with xfce 4.6.1. /usr/sbin/gdm is dated 2010-09-15 17:12. I have xscreensaver-5.08-3.1.i586 /usr/bin/xscreensaver is dated 2009-10-20 01:14 /usr/lib/xscreensaver/voronoi is dated 2009-10-20 01:16
I installed xscreensaver-gl-extras 5.12 and ran /usr/libexec/xscreensaver/voronoi directly and didn't see any warnings. I tried 7.6 and current Mesa from git. What does glxinfo say (in particular the OpenGL renderer string)? Do you see the warnings if you run /usr/libexec/xscreensaver/voronoi directly?
Hello Brian -- When I run voronoi directly -- /usr/lib/xscreensaver/voronoi I get a small black window, and, 30 seconds later, 135M of log messages in /var/log/gdm/:0.log . I attempted to send the glxinfo -v -t report as an attachment, but my message was rejected by bugzilla, so I am sending it again, this time with the report in-line (below). Thank you for your interest. I wasn't sure whether or not to label this bug critical. The bug BECOMES critical when there is no space left in the partition. I found voronoi by using a bash script to monitor the log and dump ps output when the log grows. So far, voronoi is the only program causing the problem. I have basically a clean unmodified system.

I still cant repro this bug here. But with commit 582570a04c73bc304e16af63621b594e0fc39aea at most 50 of these errors will be emitted by Mesa.
Hello Paul -- Is there anything I can do to trace or further document the problem? Have you looked at voronoi? It may be calling Mesa repeatedly, with parameters that Mesa is unable to handle. That might explain the large number of error messages. --- On Fri, 3/18/11, bugzilla-daemon@freedesktop.org <bugzilla-daemon@freedesktop.org> wrote: From: bugzilla-daemon@freedesktop.org <bugzilla-daemon@freedesktop.org> Subject: [Bug 35200] Mesa 7.6 implementation error: bad datatype in interpolate_int_colors To: ReadBetweenLines@yahoo.com Received: Friday, March 18, 2011, 2:33 AM https://bugs.freedesktop.org/show_bug.cgi?id=35200 --- Comment #3 from Brian Paul <brian.e.paul@gmail.com> 2011-03-17 19:33:05 PDT --- I still cant repro this bug here.

The large number of warnings come from the fact that this issue is hit whenever a row of pixels is drawn. That happens a lot. If you could build Mesa with gdb and set a breakpoint on _mesa_problem() and print the offending value, that would help. Or grab the latest code from git - the updated warning will emit more info.
Hello Paul -- I will need detailed step-by-step instructions here. I'd like to be introduced to Linux development utilities -- make, gdb, etc. -- and Linux internals, but that hasn't happened yet. I haven't done C++ in fifteen years (I'm a python / bash / javascript programmer). I'm eager to cooperate and learn, as long as the test doesn't destabilize my system, but you will have to guide me. --- On Fri, 3/18/11, bugzilla-daemon@freedesktop.org <bugzilla-daemon@freedesktop.org> wrote: From: bugzilla-daemon@freedesktop.org <bugzilla-daemon@freedesktop.org> Subject: [Bug 35200] Mesa 7.6 implementation error: bad datatype in interpolate_int_colors To: ReadBetweenLines@yahoo.com Received: Friday, March 18, 2011, 6:47 PM https://bugs.freedesktop.org/show_bug.cgi?id=35200 --- Comment #5 from Brian Paul <brian.e.paul@gmail.com> 2011-03-18 11:47:38 PDT --- The large number of warnings come from the fact that this issue is hit whenever a row of pixels is drawn.

The website has instructions for building Mesa. You may need to upgrade your libdrm too. Sorry, I don't have time for detailed instructions.
If someone wants a software renderer the should use llvmpipe over swrast these days. Closing as won't fix (assuming it wasn't fixed at some stage over the years).
