[vtkusers] Repeatable core using nested vtkPropAssembly under VTK 3.2.0 and X

[Eric F. Sorton]

Hi All,

I am attempting to create a hierarchy of objects.  I am using the
vtkPropAssembly class as a container.   As discussed, in the documentation, it
should be possible to create a hierarchy of vktPropAssembly.  When I create
nested vtkPropAssembly's, my application dumps a core.

I used the graphics/examplesCxx/Cone4.cxx as a base and added two
vtkPropAssembly classes.  See attached code.  When I execute this code, I get a
core dump.  Pulling up the debugger, I get the following stack trace:

#0  0x40328add in vtkProp3D::PokeMatrix () from /usr/lib/libVTKGraphics.so.3.2
#1  0x407ea3d4 in vtkPropAssembly::RenderOpaqueGeometry () from /usr/lib/libVTKCommon.so.3.2
#2  0x40277c81 in vtkRenderer::UpdateGeometry () from /usr/lib/libVTKGraphics.so.3.2

#8  0x402735b6 in vtkRenderWindow::DoAARender () from /usr/lib/libVTKGraphics.so.3.2
#9  0x40272e2b in vtkRenderWindow::Render () from /usr/lib/libVTKGraphics.so.3.2
#10 0x4032f771 in vtkXRenderWindow::Render () from /usr/lib/libVTKGraphics.so.3.2
#11 0x0804b24a in main (argc=1, argv=0xbffff9a4) at Cone4.cxx:49
#12 0x40ab917f in __libc_start_main () from /lib/libc.so.6

I am doing something wrong?  Is this a bug in 3.2.0?  Is it fixed in 4.0?  Any
information would be appreciated.

Eric
