Hi,

I just did a full update/upgrade/distupgrade and found that my versions on python-opengl and python-2.5 were equal to or greater than those you mentioned. The bug still occurs. Before we write this off as system specific, can you tell me if anything's up/what version you have of python-ctypes? I suspect the problem might be there somewhere. I need to reinstall soon anyway, I'll do a fresh install some time in the next month or two and bug you again if I can reproduce it.

Package: python-opengl
Version: 3.0.0~b3-1
Severity: important


Tested on:
  Language      Arch        Fails?
  python2.5     x86_64      YES
  python2.4     x86_64      YES
  python2.5     x86         NO
  C             x86_64      NO
  C             x86         NO

#The following Python program segfaults:
import OpenGL.GLU
OpenGL.GLU.gluNewQuadric()

This does not occur on a 32 bit system, where the operation (and my
graphics final project) run fine, nor does it occur in a similar
C program on either architecture:

#include <GL/glu.h>
int main() {
  printf("Creating new quadric: %d\n", gluNewQuadric());
  printf("All ok.\n");
}

Backtrace from python2.5:
(gdb) bt

#21 0x0000000000413989 in _start ()

While this may be related to bug #480657, that bug specifically mentions
that it only occurs under python2.5, but not 2.4. This occurs under
both. Then again, on my system so does 480657, and the backtraces do
look similar. In any case, this is a shorter counterexample so I submit it
anyway. I'm sorry, I'd troubleshoot this myself and submit a patch but
I just don't have time right now.

Best of luck,
Alex
