--- Comment #6 from Martin Liška <marxin at gcc dot gnu.org> ---
Running that under valgrind I see it started with r12-656-ga564da506f52be66:
==13643== Conditional jump or move depends on uninitialised value(s)
==13643== at 0x401148: bool compare_pairs<SomeClass*>(pair<SomeClass*>
const&, pair<SomeClass*> const&) (pr107467-2.C:12)
==13643== by 0x401176: Combined<OtherClass>::clashy() [clone .isra.0]
(pr107467-2.C:23)
==13643== by 0x4011B2: other_func() (pr107467-2.C:40)
==13643== by 0x4011ED: main (pr107467-2.C:48)
So I guess it might be something in between DSE and aliasing info investigated
by IPA modref.
@Honza: Can you take a look?
