[vtkusers] x64 build of 5.4.2 with Visual Studio 2005 crashes in vtkPolyData::ComputeBounds()

[Thuc Bui]

Hi All,

I hope someone has an idea how to proceed to debug this problem. I would
appreciate very much for any help. The same codes work fine in x86 build.
VTK 5.4.2 (the same problem for 5.4.0) is built with Visual Studio 2005 via
CMake 2.6.4, /machine:x64 on a 64-bit Vista Ultimate. It crashes in
GetPoint() when vtkPolyData::ComputeBounds() is called, and
GetNextCell(npts, pts) returns an out-of-range pts[0] at 279,172,874,241.

Below is the snippet of vtkPolyData::ComputeBounds():

   int t, i;
    vtkIdType *pts = 0;
    vtkIdType npts = 0;
    double x[3];

    vtkCellArray *cella[4];

...

  // Iterate over cells's points
    for (t = 0; t < 4; t++) 
      {
      for (cella[t]->InitTraversal(); cella[t]->GetNextCell(npts,pts); )
        {
        for (i = 0;  i < npts; i++)
          {
          this->Points->GetPoint( pts[i], x );

Many thanks in advance,
