Yes the template is not defined by we haven't done semantic analysis (and
parsing!) on it yet. It looks like by ActOnEndOfTranslationUnit the semantic
analysis still wouldn't happen unless if we see a call to that function (or
presumably other things such as its address being taken etc.) IOW if the test
case includes an instantiation of the template member, the warning doesn't
appear.
