--- Comment #8 from Martin Sebor <msebor at gcc dot gnu.org> ---
Fixed in 8.0 via r255469. GCC 8 issues the warnings below. Removing the 8
regression.
The patch seems too big to backport to older branches though it may be possible
to extract just the subset of the patch that fixes this issue and backport it.
I don't expect to have the cycles to work on in in stage 3/4 so I'll unassign
myself from the bug for now.
