--- Comment #3 from Jeffrey A. Law <law at redhat dot com> ---
Essentially a duplicate of 69989, loop optimizer deletes an edge in an
irreducible region, we schedule loop fixups, and we hit an explicit call to
verify_loop_structure before fixing up the loops.
This one hits from a different part of the loop optimizer, but it's essentially
the same bug as 69989.
