The offset causes the assembler to be sub-optimal:

.LCFI2:
        leal    -12(%ebp), %eax
        leal    4(%ebp), %edx
        .p2align 4,,7
.L2:
        movl    $1, -4(%eax)
        addl    $4, %eax
        cmpl    %edx, %eax
        jne     .L2

and I can imagine on auto-decrement targets it would be even worse (though
I didn't check).
