[Bug c++/17274] New: -Winline complains about nonexistent destructor

["mckelvey at maskull dot com" <gcc-bugzilla at gcc dot gnu dot org>]

I don't understand the warnings below. There is no destructor supplied for
std::pair, so why a complaint about a missing body? And what does "function not
considered for inlining" mean? I'm also suspicious about the "growth limit",
since the code isn't very complicated. See attachment for all warnings and
source.
