--- Comment #10 from Steve Ellcey <sje at gcc dot gnu.org> --- (In reply to Marek Polacek from comment #9) > I'll raise it with CWG; suspending until then. Not sure if it matters but there seem to be 8 instances of this problem in Boost (get_color, get_left, get_next, get_parent, get_previous, get_right, to_hook_ptr, and to_value_ptr). The actual number of errors you get during a boost build is much higher due to hitting these overload issues numerous times during the build.
