g++-11.0.0-alpha20201011 snapshot (g:4eaf96c56c1c97b11af42a4caaa12b37870308d7)
ICEs when compiling the following testcase, reduced from
test/CXX/dcl.decl/dcl.meaning/dcl.array/p3.cpp from the clang 10.0.1 test

    extern WW hz;
  }

  void
  n5 ()
  {
    kp<int[]> ();
    kp<int[1]> ();
  }
}

% g++-11.0.0 -c mtog1zuw.cpp
mtog1zuw.cpp: In instantiation of 'void pr::kp() [with WW = int [1]]':
mtog1zuw.cpp:13:17:   required from here
