The reporter claimed the source isn't valid.  Can't try clang because it
doesn't handle libstdc++ C++17 deductions.

Reduced test-case:

template  using a void;
template  class b
{
  typedef int c
} template  class b;
template ::c> class f;
template  class g;
template  class h
{
  class i;
  typedef g j class i
  {
j k
  }
} typename h::

Marek was it a valid test-case at the beginning?

I couldn't reduce it further because creduce is crashing for me.
