Doesn't look like it does to me:

That's less than 432, not less than or equal.
It ran to completion on my machine without a problem. I tried it without
any -O option, and at -O{0,2,3} without any problem. I ran it under gdb and
set a watchpoint on string[432] and it ran without tripping. So I don't know
what's going wrong for OP.
