@erichkeane I replaced every call to `LookupParsedName` which passed `nullptr`/an empty `CXXScopeSpec` and a null `QualType` with a call to `LookupName`. 

The two parameters with default arguments are forwarded to `LookupQualifiedName`/`LookupName` (the corresponding parameters for those functions also have default arguments).
