            Bug ID: 122049
           Summary: Missing warning when a deprecated class template is
                    used via CTAD in function scope
           Product: gcc
           Version: 15.1.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: rs2740 at gmail dot com
  Target Milestone: ---

template<class F>
struct [[deprecated]] X { X(F);};

void f() {
    X x{0};
}


This doesn't warn, but it should. Supplying the template argument (X<int>) does
result in a warning, as does moving the declaration to namespace scope.
