--- Comment #2 from anlauf at gcc dot gnu.org ---
A few comments: the testcase should rather be a subroutine; it will no long=
er
fail once we manage to make variables in the main implicit-save... ;-)

So a better testcase:

subroutine p
  real :: a(1:1000000, 200)
  call s (a(1:2000000, :  ))
end

We do not need optimization; the important flag is "-finline-arg-packing".
The other flags (-m32 -fsanitize=3Daddress -frecursive) are needed.

Adding a "save :: a" also avoids the ICE.=
