[Bug tree-optimization/24483] New: [4.1 Regression] ICE in ivopts

["pinskia at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Take the following code:
int f ()
{       int j0, j1, j2, j3, j4, j5, j6, j7, j8, j9, a;
        a = 0;
        for (j0 = 0; j0 < 2; j0 ++)
        for (j1 = j0; j1 < 2; j1 ++)
        for (j2 = j1; j2 < 2; j2 ++)
        for (j3 = j2; j3 < 2; j3 ++)
        for (j4 = j3; j4 < 2; j4 ++)
        for (j5 = j4; j5 < 2; j5 ++)
        for (j6 = j5; j6 < 2; j6 ++)
        for (j7 = j6; j7 < 2; j7 ++)
        for (j8 = j7; j8 < 2; j8 ++)
        for (j9 = j8; j9 < 2; j9 ++)
        a += j0 + j1 + j2 + j3 + j4 + j5 + j6 + j7 + j8 + j9;
        return a;
}
