[cfe-dev] Assertion error when attempting to iterate over RecordDecl

[Richard Smith]

This is wrong:

               if(type->isRecordType())
               {
                  const RecordType *asRecordType = static_cast<const
RecordType*>(type);

Your Type is not necessarily a RecordType here; it might be a typedef for a
record type or some other type sugar node. The right way to write this is:

               if (const RecordType *asRecordType =
type->getAs<RecordType>())
