Since rL274049, for an inheriting constructor declaration, the name of the using declaration (and using shadow declaration comes from the using declaration) is the name of a derived class, not the base class (line 8225-8232 of lib/Sema/SemaDeclCXX.cpp in https://reviews.llvm.org/rL274049). Because of this, name-based lookup performed inside Sema::LookupConstructors returns not only CXXConstructorDecls but also Using(Shadow)Decls, which results assertion failure reported in PR 29087.
