------- Comment #2 from rguenth at gcc dot gnu dot org  2010-05-17 09:39 -------
It's not a dup of PR42834 (but it might be the same issue as PR42832 which
was a libstdc++ bug or a frontend bug).

It happens to work on trunk, so it might also be a dup of PR43987 (though
unlikely), rather different inlining might have made the bug latent.

I can confirm the observed effect.  I didn't investigate on whether this
is a bug in boost or not (we're changing our minds on what is valid and
what not all the time anyway).
