[Paraview] Debbuging vtkEnSight6BinaryReader.cxx: this->FileSize is negative: type int being used for FileSize

[Peter J. Bismuti]

The EnSight reader is exiting after an assertion fails based on the file size.  
Notice I have stuck in an additional error message printing out data. 

It is saying the file size is negative.   Has anyone seen this error before?  
The type of FileSize is an integer.  What if the size is larger than the 
range of int? 

The file size is being set at line 92:


    struct stat fs;
  if ( !stat( filename, &fs) )
    {
    // Find out how big the file is.
    this->FileSize = (int)(fs.st_size);
