Ok, try this one :-)
int main(int argc, char *argv[])
{
int i = 1;
short s = 2;
pointer p = (argc > 1) ? &i : &s;
return *p;
}
In this simple example the compiler could generate code to check the
value of argc and dereference p correctly, but I don't think it would
be practical (possible?) for more complicated examples.
