[vtkusers] Crash when reading LSDyna d3plot file

[Simon ESNEAULT]

Hello All,

I'm getting a crash when trying to load a d3plot file coming from LSDyna
R8, using the vtkLSDynaReader class.

Attached is a very simple code that reproduces the problem (at least here
on Windows 7, VTK 6.3). It is written to be used with these dataset :
https://www.dropbox.com/s/2gzah0d8d2dpvlt/d3plot.zip?dl=0

It may come from our dataset it self, because when I change the line :
l_reader->SetFileName( "./our.d3plot" );
by the line
l_reader->SetFileName( "./hemi_draw.d3plot" );
The hemi_draw dataset loads just fine (it is coming from the VTKLargeData
git repository)

Or maybe the problem comes from my code, because ParaView is able to load
the dataset ...
Any clue ? Any d3plot expert around ?

Thanks

Simon
