Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Target Milestone|--- |4.9.0 --- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> --- Surely frontend related - after gimplification I see B::B() (struct B * const this, const void * * __vtt_parm) { struct B * <retval>; <retval> = B::B (this, 0, __vtt_parm); } which misses a return.
