            Bug ID: 107085
           Summary: __reference_constructs_from_temporary does not detect
                    static up-cast
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: roi.jacobson1 at gmail dot com
  Target Milestone: ---

This example:

struct Base {};
struct Derived : Base {};
static_assert(__reference_constructs_from_temporary(Base&, Derived));

fails to compile, but according to p2255r1 it seems correct to me.=
