[Paraview] mesh file with a core dump

[Umut TABAK]

Dear all,

2 or 3 years ago, I coded a simple interface to the commercial finite
element code ANSYS.
It was working fine at that time. Mainly, it is a simple python interface
which generates an ASCII *.vtk file in the legacy format, version 2.0.

I tried to use the same interface tonight and with the latest version I can
open the file, but if I click apply, paraview aborts with the following
message.

*** Error in
`/home/utabak/external_programs/ParaView-5.2.0-Qt4-OpenGL2-MPI-Linux-64bit/lib/paraview-5.2/paraview':
free(): invalid next size (normal): 0x0000000003255440 ***
Aborted (core dumped)

I tried on a simpler domain to debug a bit, but the input file seems fine
to me. Moreover, I can open the same vtk file in another open source mesh
generator, which is quite popular, namely, Gmsh without any errors.

So I am wondering the reason for this problem. I also attached the input
vtk file for your reference.

Any help is appreciated.

BR,
Umut
