--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Can happen when loop fixup removes and then re-discovers a loop.  You can scan
-details dumps for 'fix_loop_structure: ...' messages.  But I can only
see

t.ii.041t.cddce1:fix_loop_structure: removing loop 1

there.  I'll have a look.
