Summary0002912: VRML segfaults when PROTO is used
DescriptionAttached is a VRML file and a Python script that crashes when run.
The Python script that causes the crash is as follows:

#----------------------------
import vtk
ren = vtk.vtkRenderer()
rw = vtk.vtkRenderWindow()
rw.AddRenderer(ren)
i = vtk.vtkVRMLImporter()
i.SetFileName('mayavi-crash.wrl')
i.SetRenderWindow(rw)
i.Read()
rw.Render()
#----------------------------


Drew Parsons <dparsons@users.sourceforge.net> submitted this error
report against mayavi on the Debian bug tracker.

 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=346182 [^]


I get the following backtrace with VTK-5.0.

I filed the original bug. I can also get a segfault now without PROTO, for instance with a simple DEF:

#VRML V2.0 utf8
DEF medColour Material { emissiveColor 0 1 0 }

(that's it, but I can add a shape too if you like :) )

The backtrace on Prabhu's script, segfaulting at i.Read(), is similar to his, ending at
#0 0xb619fab6 in vtkVRMLImporter::exitField () from /usr/lib/libvtkHybrid.so.4
#1 0xb61a53e9 in yyparse () from /usr/lib/libvtkHybrid.so.4
#2 0xb61a57eb in vtkVRMLImporter::ImportBegin ()
   from /usr/lib/libvtkHybrid.so.4
#3 0xb65ef658 in vtkImporter::Read () from /usr/lib/libvtkRendering.so.4
#4 0xb67d9aee in PyVTKClass_vtkImagingFactoryNew ()
   from /usr/lib/python2.3/site-packages/vtk_python/libvtkRenderingPython.so
