--- Comment #8 from Martin Sebor <msebor at gcc dot gnu.org> ---
With the libstdc++ patch committed in r255753 the warning is no longer issued.
Pursuant to Jeff's comment #7 I've removed the regression marker and retitled
the bug.
To reproduce the missing optimization (and the warning) the libstdc++ patch
needs to be reverted.
