Confirmed.
The following testcase crashes on i686-pc-linux-gnu when compiled with
"-O -ftree-vectorize -msse2":
======================================================
void foo(int* __restrict__ p, int* __restrict__ q)
{
int i;
for (i=0; i<2; ++i)
p[i] = q[i] = 0;
}
======================================================
