Summary0012753: Segfault when reading .vti file written by VTK itself
DescriptionThe attached Python script creates an vtkImageData of 2000x2000x834 uint8 scalar values. It saves this to a .vti file using vtkXMLImageDataWriter.
When trying to read it back in with vtkXMLImageDataReader the reader segfaults.
Found on an actual DICOM dataset that I wanted to store as a .vti.

This is with VTK 5.8.0 on an Ubuntu 10.04.3 x86_64 system.

Relevant stack trace and valgrind error (looks like null pointer being dereferenced):

 Looks like the calculation of volumeTuples (vtkXMLStructuredDataReader.cxx:403) overflows:

vtkXMLStructuredDataReader::ReadSubExtent...
{
...
      vtkIdType volumeTuples =
        (inDimensions[0]*inDimensions[1]*inDimensions[2]);
...
      if(!this->ReadArrayValues(da, destTuple*components, array,
          sourceTuple*components, volumeTuples*components))
...

Number of voxels = 2000*2000*834 = 3336000000

3336000000 - 2^32 = -958967296

 After realizing I had VTK_USE_64BIT_IDS set and therefore vtkTypeId becomes a 64-bit value as well ("long long") I tried some stuff:

paulmlocal@sara11006:~/c/vtk-5.8.0-release$ cat t.cc
#include <cstdio>
int
main()
{
    // Set up values similar to VTK code
    int i = 2000, j = 2000, k = 834;

    long long v = (i * j * k);
    printf("%lld\n", v);

    long long w = ((long long)i * j * k);
    printf("%lld\n", w);
}

paulmlocal@sara11006:~/c/vtk-5.8.0-release$ g++ -o t -W -Wall t.cc
paulmlocal@sara11006:~/c/vtk-5.8.0-release$ ./t
-958967296
3336000000

Ouch.....

That's quite unexpected behaviour at first glance, but makes sense after realizing that the values being multiplied are 32-bit integers, so the result will be 32-bit as well.

Interestingly, you get warned when using literals :)

paulmlocal@sara11006:~/c/vtk-5.8.0-release$ cat t2.cc
int
main()
{
    long long v = 2000 * 2000 * 834;
}

paulmlocal@sara11006:~/c/vtk-5.8.0-release$ g++ -o t2 t2.cc
t2.cc: In function ‘int main()’:
t2.cc:4: warning: integer overflow in expression
