In my reply to HJ I said I'd spotted it in 20021024, it was actually
20021025.  However, it is gone in 20021031.  So I'll close it.  However,
it seems wise to have a regression test.

Would someone with appropriate write permission please create a regression
test with the following code?  We're just testing for successful
compilation (though the test could be extended to verify that the correct
results are computed).

void ice(int m, int n, double *f) {
    int i, j, k;

    k = 1;  /* ICE */

    for (j = 0; j < n; j++) {
        for (i = k; i < m; i++) {
            f[i] = (double) (i * j);
            f[i + j] = (double) ((i + 1) * j);
        }
    }
}
