[Matheus Izvekov via Phabricator via cfe-commits]

mizvekov added a comment.

FYI this is a minimal repro taken from Martin's preprocessed source (Thanks!):

  template <class> struct a { using b = const float; };
  template <class c> using d = typename a<c>::b;  
  
  template <class c> void e(d<c> *, c) {}
  template void e(typename a<void>::b *, int);
