[Paraview] Reader Problem

[Brian Dotson]

Hi all,
 
I wrote a custom reader that brings our simulation results into
ParaView.  
 
The data is an unstructured grid with multiple timesteps.  The cells
are either hexahedron or wedges.  The data I attach to the mesh is
mostly scalar with a few vectors.
 
With most of the simulation results we look at the reader looks fine,
but some of the data sets cause the following error.
 
free(): invalid pointer 0xc2f7f70!
 
This error happens after my code executes and I have returned the
unstructured grid over to ParaView.
 
I have done the following to debug the problem:
 
1. I checked the number of arrays that I am attaching to the mesh and
the NumberOfCellFields variable, these match.
 
2. I checked the MaxId of all the arrays.  These match the cell count.
 
3. When I turn all the cell arrays off, I don't get the errors, and the
mesh loads.
 
Does anyone have any ideas on what the problem could be?
 
Thanks,
