A broken diagnostic is issued since GCC 4.0.0 for the following code snippet:

===============================================================
struct A
{
  virtual A foo();
};

void bar(A& a)
{
  a.foo()=0;
}
===============================================================

bug.cc: In function 'void bar(A&)':
bug.cc:8: error: no match for 'operator=' in '#'obj_type_ref' not supported by
dump_expr#<expression error>() = 0'
bug.cc:2: note: candidates are: A& A::operator=(const A&)
