--- Comment #1 from DJ Delorie <dj at redhat dot com> ---
If elsewhere calls foo(500) you will get an actual out of bounds access.  I
think the warning is appropriate.  Have you tried checking the value of 'order'
in that function, before the loop, to validate its value?  Such a check might
fix your bug and silence the warning.
