--- Comment #14 from Richard Biener <rguenth at gcc dot gnu.org> ---
Btw, eventually the refactoring done for PR105142 in r12-8012-gfc8d9e4497032d
will help, at least the fixed problem is of similar nature.
The original testcase seems fixed by this at least as we are no longer
expanding the guarded c + 1.
