             Bug #: 11577
           Summary: "[self alloc]" in a class method not inferred to
                    return an instance of that class
           Product: clang
           Version: trunk

         Component: Frontend

test case

The result of +alloc should be inferred to be an instance of the receiving
"self" class here, but is apparently just being typed as "id". This cause clang
to think the -initWithContentsOfFile: and -initWithContentsOfURL: are possibly
the deprecated methods in Foundation.
