Excuse me if this is already a well-known bug, but I don't read this
group regularly.  Consider the following program:

#include <stream.h>

class P {
public:
  virtual void hello() { cout << "hello\n"; }
  void callhello() { hello(); }
};

class C : public P {
public:
  virtual void hello() { cout << "hullo\n"; }
};

void g(P x) { x.callhello(); }	// should call P::hello()

int main() {
  C z;
  z.hello();			// calls C::hello()
  g(z);				// results in an erroneous call to C::hello()!
}

When compiled with g++ 2.2.2 under SunOS 4.1.2, this program produces
the erroneous output
	hullo
	hullo

This is incorrect, since the x is a value parameter, whence
dispatching should be static.

Compilation with AT&T CC correctly results in
	hullo
	hello

Have other people observed this problem?
