            Bug ID: 104225
           Summary: accepts-invalid new expression that uses deleted
                    implicit default constructor of class specialization
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ppalka at gcc dot gnu.org
  Target Milestone: ---

The following testcase compiles without error, but should be rejected because
it uses B's deleted default constructor:

class A { ~A(); };
template <class> class B { A f = 1; };
int main() {
  new B<int>;
}
