            Bug ID: 111230
           Summary: show explicit functions in possible candidates
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3

  Target Milestone: ---

struct T {
   T() { } // #1
   explicit T(const T&) { } // #2
};

void
g ()
{
   T t{};
   throw t;
}

shows

h.C: In function =E2=80=98void g()=E2=80=99:
h.C:10:10: error: no matching function for call to =E2=80=98T::T(T)=E2=80=99
   10 |    throw t;
      |          ^
h.C:2:4: note: candidate: =E2=80=98T::T()=E2=80=99
    2 |    T() { } // #1
      |    ^
h.C:2:4: note:   candidate expects 0 arguments, 1 provided
h.C:10:10: note:   in thrown expression

but it never mentions #2.=
