Indeed! I can confirm that this fixes the bogus warning on comment 0 and 4 and
also in a larger code base, where I first observed it (four-fold).

Thanks for the quick fix! That patch is ok for trunk and gcc-6 from my side.

Could you explain how/why it fixes the problem? Or where the problem came from
in the first place?
