Summary

0007082: vtkMetaImageReader fails on a simple 256 x 256 signed short file

Description

Running the attached python example on the included fixed.mhd breaks in one of two ways:
1. either the vtkMetaImageReader complains that it cannot allocate 1.5 million 2 byte units
2. if 1. coincidentally does succeed, the GetScalarRange() segfaults (an access violation - null pointer deref - on Windows)

Additional Information

We checked and double-checked this on Windows XP (SP2 and SP3) with a VS.NET 2005 build of the ParaView-3-2-1 tagged VTK, as well as on Ubuntu 7.10.

Example back trace of case 2:
