>Description:
This is accepted by the current snapshot,

class foo {
public:
  foo() {};
  void throwMe () {
    throw *this;
  };
  virtual void test () = 0;
};

As far as I know, this code should be refused as it is not
possible to create a temporary of type foo for throwing
*this (foo has a pure virtual member function test).

Previous version of g++ (2.8.2) rejected the code as does
the other compilers I've access to (comeau online driver,
IBM xlC, HP aCC) except SparcWorks.
