Here's a funny little one... 
....coutesy of Bruce Anderson, Dept. of ESE, Essex University

/* funny in reference argument checking and execution
   This code does not compile with AT&T 1.2; with g++ 1.35
   it gives
                99--99--99.1
                0--0--8.48798e-315
   This can't be right!
   My own belief is that it should fail to compile; otherwise
   how about correct coercion both ways?
*/
 
#include <stream.h>

void zap(int& x) { x = 0; }

main()
   {    int i = 99; double d = 99.0; double d1 = 99.1;
        cout << i << "--" << d << "--" << d1 << "\n";
        zap(i);
        zap(d);
        zap(d1);
        cout << i << "--" << d << "--" << d1 << "\n";
   }
