[Insight-users] Weird behavior fo itk::Image<>::RegionType

[Gabriel Santiago]

The weirdest thing is, if I replace the variables *
desiredRegion.SetSize(size)* and* desiredRegion.SetIndex(start)* inside for*
**desiredRegion.SetSize(inputRegion.GetSize()*) and *desiredRegion.SetIndex(
**inputRegion.GetIndex()*) respectively, it doesn't appear the error
message and the program compiles just fine.
