When I compile this program:

---------- cut here for bug.cpp -------------------
#include <iostream.h>
#include <string.h>

struct sorry{
    const char *error_msg;
    sorry( const char *p) : error_msg(p) {}
};

int main()
{
    try {
        throw sorry( "test 3");
    }
    catch ( sorry stuff ) {
        cerr << "Sorry, ";
        cerr << stuff.error_msg ;
        cerr << '\n';
    }
    cout << '\n';
}
---------- cut here for bug.cpp -------------------

with gxx version 2.8.1
using this:
   gxx -g -Wall bug.cpp -o bug.exe
I get this:
  bug.cpp: In function `int main()':
  bug.cpp:14: warning: value computed is not used
  
Can someone tell me which value is not used?
