ICE confirmed. I am not so sure that this is invalid code.
NAG accepts it, and I believe it is right.
(a(2:1)) should have shape=[0], len=3

--- Comment #2 from anlauf at gcc dot gnu.org ---
It is probably easier to compare
character(*), parameter :: b(*) = (a(2:1)) ! ICE
vs.
character(*), parameter :: b(*) = a(2:1) ! no ICE

We need to handle zero-sized constructors.
