Please check the compiler using the example code in gcc bug38480

foo.c

unsigned short foobar;
int array[100];

void g(unsigned short j) {
  if (j < 100)
    array[j]++;
}

void f() {
  int i = foobar;
  if (i >= 100)
    g(foobar);
}

# gcc -O3 -Wall -c foo.c

In my machine RHEL5U3,  outputs:
$ gcc34 -O3 -Wall -c foo.c
$ gcc -O3 -Wall -c foo.c
$ gcc43 -O3 -Wall -c foo.c
foo.c: In function ?f?:
foo.c:6: warning: array subscript is above array bounds
foo.c:6: warning: array subscript is above array bounds

And the results  of executing example stap script 
are like above.
