Jonathan Wakely <redi at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution| |DUPLICATE --- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> 2011-09-07 12:56:49 UTC --- TR1 says that tr1::bind returns a forwarding call wrapper, where "A forwarding call wrapper is a call wrapper that can be called with an argument list t1, t2, ..., tN where each ti is an lvalue. The effect of calling a forwarding call wrapper with one or more arguments that are rvalues is implementation defined." So TR1 is pretty clear that it only needs to support lvalue arguments. *** This bug has been marked as a duplicate of bug 35569 ***
