As an alternative to finding a spec, if you can clearly demonstrate that the
observable behavior of calling a pure virtual function is to call this particular
function, then I believe we can accept this.  For example, what happens
when you run this program?

struct A {
  virtual void foo() = 0;
  A() { foo(); }
};
struct B : A{
  void foo() {}
};
int main() {
  B b;
}
