Bug 123762 – 3ddesktop segfaults with software rendering on amd64

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Samuele Kaplun 2006-02-22 16:02:38 UTC]

Hi, with 3ddesktop-0.2.9, xorg-server-1.0.1-r4, mesa-6.4.2-r1, if I run "3ddeskd -v" it segfaults with this messages:
Verbose is ON
load_conf: opened /etc/3ddesktop.conf

I've recompiled 3ddesktop with debug information and this is the stack I've obtained:
#0  0x00002aaaab70d9bf in glClearColor ()
   from //usr/lib64/opengl/xorg-x11/lib/libGL.so.1

I'm using the radeon opensource driver with xorg-x11 opengl drivers in software rendering mode (since my card, a Radeon Xpress 200m, isn't supported yet).

This is my emerge --info:

Only today I managed to get software rendering working with the last releases of xorg-server and mesa. I'm certaing the problem concern these pieces of code.

[Comment 1 Krzysztof Pawlik (RETIRED) 2006-02-25 13:40:53 UTC]

3ddeskd.cpp:2122 is:

    glClearColor(0.0f, 0.0f, 0.0f, 0.0f);

And the segfault occurs inside glClearColor() call. It's not 3ddesktop issue. Do other GL apps work ok?

[Comment 2 Krzysztof Pawlik (RETIRED) 2006-03-03 02:45:04 UTC]

Works for me, please reopen if you have more details.

[Comment 3 Samuele Kaplun 2006-03-03 02:47:18 UTC]

Well I now think this bug concerns my 3d system configuration. So I'll keep it resolved :-)

Created attachment 207811 [details, diff]
OpenGL calls moved after OpenGL initialization.

It seems, that the OpenGL functions are called before the OpenGL is properly initialized that may result in SIGSEGV on some architectures/video drivers (e.g. with intel_video).

You should have opened a new bug, instead of commenting on 3 years old one...

But since I've noticed this by accident -> Reopening
