[cfe-commits] [Review Request]Polymorphic Pointers Checker

[Jim Goodnow II]

This checks for the implicit casting of an array of a derived type to a 
base pointer. This is problematic because if the base pointer is 
incremented or indexed, a size difference between the base and derived 
classes could result in a bad pointer calculation. I could check for the 
sizes of the two classes to see if they happen to be the same, but it's 
really just a bad practice, since the size could change on a later revision.
