--- Comment #12 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Just going from the demangled name of
std::pair<std::chrono::time_point<ceph::mono_clock,
std::chrono::duration<unsigned long, std::ratio<1l, 1000000000l> > > const,
Context*>
it would surprise me if it was ODR violation in the testcase, because class
Context
is only defined in Timer.ii, not in the other preprocessed source,
ceph::mono_clock is defined in both but looks the same (and it is empty cla=
ss
anyway), and the pair uses Context* as second type anyway, so it is unclear=
 how
it could become something smaller than pointer.
But, admittedly I haven't looked up at this under the debugger and not even
sure where to look at that.=
