Jason Merrill <jason at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution| |FIXED Target Milestone|--- |4.6.1 --- Comment #5 from Jason Merrill <jason at gcc dot gnu.org> 2011-05-06 13:46:36 UTC --- Yes, this will be fixed in 4.6.1 (by http://gcc.gnu.org/ml/gcc-patches/2011-03/msg00848.html) The function definition is ill-formed, no diagnostic required, because there is no set of arguments that will make it a constant expression. But I don't think it's worth trying hard to diagnose it at the point of definition since we'll complain when it's used.
