Some gcc compilers have problems with vtkResliceFloor
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
The gcc 3.4 compiler on RHEL (though not the gcc-3.4 one on Fedora) mis-compiled the vtkResliceFloor code. This can result in incorrect results and segfaults with vtkImageReslice with this particular compiler.
The code from the main branch should be backported to VTK 4.2 and also to VTK 4.4. VTK 5.0 already has the fix.
