--- Comment #11 from Thomas Koenig <tkoenig at gcc dot gnu.org> ---
Test case from comment#4 passes, test case from comment#9 ICEs:

program p
  type t
    integer :: m(1,1)
  end type
  type(t), parameter :: x(1) = [ t(789) ]
  integer :: f(1,1)
  f = (x(1)%m)
  print *, f
end

Bitte senden Sie einen vollständigen Fehlerbericht auf Englisch ein;
inclusive vorverarbeitetem Quellcode, wenn es dienlich ist.
Please include the complete backtrace with any bug report.
Weitere Hinweise finden Sie unter »<https://gcc.gnu.org/bugs/>«.

So, we should probably commit the test case from #4.
