--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
I think this boils down to jump threading -- FSM threading should be able
to notice that after setting running to false we should can exit the loop nest.
Likely that doesn't work for the nest but just for the inner loop for some
reason.
