[vtkusers] Strange segmentation fault problem, Debian GNU/Linux and vtk

[Jason Ruiter]

Greetings,

I've been having a strange problem with vtk4 recently.

The specifics:

I'm running Debian GNU/Linux.  I've tried this on both woody and sid. 
(Woody runs Xfree86 4.1 and Sid runs Xfree86 4.2).  It happens on both
vtk3.2 and vtk4.0.  I get the same behaviour from Nvidia Geforce4 128MB
(both the nvidia and nv X drivers) and an ATI Radeon with 64MB.

I try to load a large volume of raw RGB data and render it.  (view.py,
attached).  It loads the data, puts up a render window, then segfaults. 
Granted, its a large volume (50MB), but I've been able to render volumes
this size on a Redhat 7.3 box with no problem  The same happens for
polydata with large numbers of triangles (200,000 or more).  Again, this
works on a RedHat 7.3 box with an identical card.

I realize this probably isn't strictly a vtk problem.  Just wondering if
anyone else has seen this behaviour, especially if they're using Debian.

Any help and/or pointers appreciated.

Thanks
