================
Comment at: clang/lib/AST/Type.cpp:3374
     auto &ExtraBits = *getTrailingObjects<FunctionTypeExtraBitfields>();
-    ExtraBits.NumExceptionType = epi.ExceptionSpec.Exceptions.size();
+    auto NumExceptions = epi.ExceptionSpec.Exceptions.size();
+    assert(NumExceptions <= UINT16_MAX &&
----------------
So this isn't a place where we're allowed to use `auto`.  We can only use it if the type is listed on the RHS (like in the case of casts/etc).
