page fault on read access in libgl.so.1

[Jérôme]

I tried to run a wine application which is using libgl.so.1.

At first I reported a bug into the wine bug tracking system:
http://bugs.winehq.org/show_bug.cgi?id=23109

The developpers told me there was a bug into my video driver.

See the attached debug stack trace for details.

Created an attachment (id=36371)
the log of the crash

version: 8.723.1

I attached the log.

[Jérôme (jerome-bouat)]

This bug still appears with all updates available up to now (fglrx*, nvidia-current-modaliases).

This bug prevents me to test a wine bug.

[Jérôme (jerome-bouat)]

I change the severity to "critical" since my application crashed.

[Felix Kuehling (felix-kuehling)]

The problem sounds like it's using the wrong version of libGL.so.1. Check the output of "ldd /usr/bin/fgl_glxgears" for example. If it uses libGL.so.1 from /usr/lib, that's wrong. If you're using the Ubuntu packages of fglrx, it should be using /usr/lib/fglrx/libGL.so.1 and there should be no /usr/lib/libGL.so*.

[Felix Kuehling (felix-kuehling)]

Hmm, I looked at your Xorg.0.log and lspci output. You're using a Mach64-based card. This card is not supported by the fglrx driver. In your case having fglrx installed actually breaks the Mach64 driver. I recommend you uninstall fglrx. That will give you as much functionality and performance as you'll be able to get on this hardware.

[Jérôme (jerome-bouat)]

It seems this driver isn't suitable for my graphic adapter (Rage Mobility).

[Jérôme (jerome-bouat)]

You're right. I removed the fglrx driver and it seems to work (no segmentation fault anymore).
