--- Comment #1 from Jakub Jelinek  ---
Started with r236615 and got fixed on the trunk with r253600.

Reduced testcase:

// PR c++/84496
// { dg-do compile { target c++14 } }

template  struct C { static constexpr T D = n; };
struct E : C {};
template  struct F : C {};
template  T foo ();
template  struct H { typedef int G; };
template  class I;
struct L;
template  struct J;
template  struct K;
struct R {
  template 
  static J () (foo...)), L> o;
};
template  struct K : R {
  typedef decltype (o) G;
};
template 
struct D : K::D, P, Q...> {};
template  struct I : D {};
template  class function;
template  struct function {
  template ::G> struct C;
  template  using U = int;
  template , typename = U>
  function (P);
};
template 
template 
function::function (P)
{
}
void bar (function);

void
baz ()
{
  auto a = [] {
static int counter;
bar ([] (auto) { counter++; });
  };
}

Will commit the testcase to trunk now to make sure we don't regress it again.
