--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
We have

falign-loops
Common Report Var(align_loops,0) Optimization UInteger
Align the start of loops.

falign-loops=
Common RejectNegative Joined UInteger Var(align_loops)

so maybe behavior WRT non-Optimization marked "aliases" changed?

Confirmed it works with GCC 6.
