void fdct_int32()
{
        int tmp4, tmp5, tmp7;
        int z1, z2, z3, z4, z5;
        int *dataptr;
        int i;

        for (i = 0; i < 8; i++) {
                tmp7 = dataptr[0];

                z3 = tmp4;
                z4 = tmp5 + tmp7;
                z5 = (z3 + z4) * ((int) 9633);

                z3 += z5;

                dataptr[56] = tmp4 + z1 + z3;
                dataptr[40] = tmp5 + z2 + z4;

                dataptr++;
        }
}

When compiling the above file with the following command line arguments:
gcc -c -O -march=pentium4 -ftree-vectorize foo.c

I get the following error:
foo.c: In function 'fdct_int32':
foo.c:22: internal compiler error: in push_reload, at reload.c:1303
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

I discovered this while trying to compile the xvid sources using silly CFLAGS
by accident. The above file is a somewhat reduced testcase.
