Confirmed.

Reduced testcase that crashes with -O -ftree-vectorize -march=pentium4:

================================
int foo(int j)
{
    int i, a[4];

    for (i = 0; i < 4; i++)
        a[i] = j << 1;

    return a[0];
}
================================

I encountered this bug too with a very similar code on GCC 4.1 snapshot 20050424
with options -O2 -msse2 -ftree-vectorize.
