Jason Merrill <jason at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution| |INVALID --- Comment #1 from Jason Merrill <jason at gcc dot gnu.org> 2011-05-25 15:35:09 UTC --- A nested namespace of an inline namespace does not map onto a nested namespace of the enclosing namespace; you need to have one chrono namespace and two inline namespaces, rather than one inline namespace and two chrono namespaces.
