[cfe-dev] FieldDecl::getParent() not working in Objective C code?

[Reid Kleckner]

Sounds like an obj-c bug. The FieldDecl is probably actually an
ObjCIvarDecl, and you probably want to use getContainingInterface() instead
if it is. ObjCInterfaceDecl don't inherit from RecordDecl, so getParent()
can't work as written.
