--- Comment #5 from Jason Merrill <jason at gcc dot gnu.org> --- Author: jason Date: Tue Mar 12 03:19:22 2019 New Revision: 269602 URL: https://gcc.gnu.org/viewcvs?rev=269602&root=gcc&view=rev Log: PR c++/86521 - wrong overload resolution with ref-qualifiers. Here we were wrongly treating binding a const lvalue ref to an xvalue as direct binding, which is wrong under [dcl.init.ref] and [over.match.ref]. * call.c (build_user_type_conversion_1): Don't use a conversion to a reference of the wrong rvalueness for direct binding.
