Description Nicolas Aspert 2002-05-22 08:57:08 EDT
Description of Problem:
An Qt-OpenGL app crashes (segfault) inside the constructor of a QGLWidget. The
same app runs smoothly on RH-7.2 (Qt 2.3 and 3.0.3), whereas it is not possible
to run it correctly on RH-7.3 (with both Qt-2.3.1 and Qt-3.0.3)

Version-Release number of selected component (if applicable):

How Reproducible:
Easily (cf. below)

Steps to Reproduce:
1. Build the 'Mesh' app. (see attachment)
2. In the top directory of Mesh, issue the following command :
./bin/mesh venus3_s.wrl venus3.smf
3. D'oh !

Actual Results:
Segfault. (Inside QGLWidget constructor)

Expected Results:
Nice visualization window. 

Additional Information:
The program runs correctly with a freshly-built Qt-3.0.4 (except for a segfault
when quitting, which may be my fault)	
The problem might be related to the use of a NVidia ^&* closed-source driver.

Harald: Is your glweak hack messing up? 
[Now that libGL is part of XFree86, I guess we can remove it anyway]
Comment 4 Harald Hoyer 2002-05-22 09:12:29 EDT
if it works with the removed tweak...
we really can remove it, if there is no more Mesa

It's fixed in current release.
