>Description:
I have a class which defines an operator<< so that it can be dumped to cout or cerr.  I cannot call this function from gdb.  I have searched the bug database and while this problem has been reported before and some solutions were presented, none of them worked using gdb 6.0, gcc 2.95.3


class MyClass
{
public:
  int     mInteger;
  double  mDouble;
};
 
ostream & operator<< (ostream & s, const MyClass & o)
{
  s << o.mInteger << " " << o.mDouble << endl;
  return s;
}
>How-To-Repeat:
Put a breakpoint on the attached file @ line 22.  Then try to call the operator<< function defined on line 12.

compile with g++ -g -o test deleteme.cpp

Don't know.
