            Bug ID: 61135
           Summary: It seems to be not able to call virtual method of
                    literal object in lambda expression

            Status: UNCONFIRMED
          Severity: normal

         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: okamoto6496 at gmail dot com

Code is below:

  1 struct Base
  2 {
  3         virtual int b() const{return 1;};
  4 };
  5 
  6 struct Super:Base{};
  7 
  8 int main()
  9 {
 10         constexpr Super s;
 11         []{s.b();}();
 12 }

Compiler message is below:
