--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Similar to the other bug - when 'main' is named 'bar' then we optimize it O=
K at
-O3, the difference being again loop header copying not applied in "cold"
context
but inlining is.

Not sure if we want to call this a bug, but then the inconsistency is odd.=
