Summary: glCallLists crashes without Numeric

Initial Comment:
I am using PyOpenGL-2.0.0.44.win32-py2.2.exe and had to write this 
workaround:
        # The following two lines work with Python2.1, but 
crash with Python2.2,
        # so we have to loop over all characters
        # 
glListBase(self.fontlist_index)
        # glCallLists(text)
        for c 
in text:
            glCallList(self.fontlist_index + ord(c))

Is it 
just me or can anyone verify this?

Given the rarity of the error, and the futility of running
OpenGL without Numeric, I am marking this closed.  2.0.1
explicitly depends on Numeric, regardless of the internal
attempts to recover in those situations where it is absent.

Although Numeric is theoretically optional, I don't think
I've tested with a non-Numeric-enabled Python in ages (Tarn
may do those tests, however).  All of my own code uses
vertex arrays and the like, so Numeric is basically a
requirement for anything I work with.

Suppose the proper thing to do is strip out Numeric and see
which tests fail.  Will put it on the todo list.

After installing Numeric-21.0.win32-py2.2.exe everythings 
works as expected. I thought Numeric was optional. Rename 
Numeric.pth to .pth2 to see the crash.
The Python2.1 vs 2.2 
issue was misleading. 2.1 had Numeric installed on my 
machine, 2.2 not.

Thanks,
Michael

Well, I can't get the sample code (thank-you) to trigger an
error.  I'm using Python 2.2.1 with the latest PyOpenGL
binary distribution for Python 2.2 and wxPython 2.2.3pre3. 
(This is under Win2K with an ATI Radeon 7500).  I can even
see the text getting properly displayed.

Can you try upgrading to equal versions of each lib to see
if that fixes the bug for you?  Any other suggestions for
replicating the problem?

Could you give me a piece of sample code that exercises the
error?  I'll see if I can get my C-coding friend to look at
it if I can just pass her a small piece of code that
triggers the crash.
