================
Comment at: clang/lib/Sema/SemaTemplateInstantiateDecl.cpp:557-558
+ dyn_cast_or_null<CXXRecordDecl>(ND->getDeclContext());
+ CXXThisScopeRAII ThisScope(*this, ThisContext, Qualifiers(),
+ ND->isCXXInstanceMember());
+ }
----------------
The purpose of creating this is to change the type of `this` in the scope of the instantiation below, so this change is incorrect. The right fix would be to change the initializer of `ThisContext` to handle `ND` being null. (I suspect that actually can't happen at the moment because we happen to only attach late-parsed attributes to `NamedDecl`s, but I don't think there's any fundamental reason why that should be the case so it makes some sense to retain the check here.)
