I've tried. It's Octaviz[1] that's using VTK. I have an Octave script
that I've only managed to get a consistent segfault with some data
set, but I haven't managed to simplify the test case and still get a
segfault.
While I decide if the problem is in Octaviz or VTK, I've submitted a
Debian bug on Octaviz[2] and I'll try debugging this one myself. The
segfault does happen several calls deep into VTK proper. If you'll
excuse the tangle with Octaviz and Octave, below you will find a stack
trace, without debug symbols for VTK If you think it would be helfpul
to compile VTK with debug symbols and produce another stack trace, let
me know. It's mostly out of impatience that I don't have VTK with
debug symbols, because it takes a looooong time to compile VTK. ;-)
You'll observe that the last bit of Octaviz code (which is really VTK
code wrapped with the proper incantations to be called from Octave)
called on #9 of stack trace below before going into VTK proper is
this, from vtkAlgorithm.cc:
/* ah virtual void Update (); */
error_flag = 0;
if (!error_flag)
{
vtk_pointer->Update(); // segfault here
return retval;
}
}
Hope I provided somewhat relevant information...
Cheers,
