--- Comment #5 from janus at gcc dot gnu.org ---
The ICE and backtrace one gets on all variants of the test case has changed
slightly to:


internal compiler error: in tree_to_uhwi, at tree.h:3653
      class(rng_t), allocatable :: rng

Not sure if this is actually a Frotran problem or rather originates from the
middle-end ...
