--- Comment #1 from Richard Smith <richard-llvm at metafoo.co.uk> ---
I can't reproduce this with trunk, nor 3.6, but it reproduces with 3.5. Looks
like this has been fixed for a while. I remember we had (and fixed) a bug
analyzing loops with an N bit induction variable that perform exactly 2^N
iterations; that could be the bug you hit.
