------- Additional Comments From francois dot rigault at amadeus dot com  2009-03-11 16:34 -------
I have the same bug here
GDB 6.8.50.20090311 tarball
GCC 3.4.2

I'm reproducing it with the cpp file below.
--------
class MyClass
{
public:
  bool
  operator()() const
  {
    return true; // put a breakpoint here and run
  }
};

int
main()
{
  MyClass a;
  a();
  return 10;
}
--------
The core shows :
