[pypy-issue] [issue1072] Fatal RPython error: OverflowError

Thanks for the pointers :)

I find that:
> pypy --jit
enable_opts=intbounds:rewrite:virtualize:string:earlyforce:pure:heap:ffi break.py

runs to completion, while

> pypy --jit
enable_opts=intbounds:rewrite:virtualize:string:earlyforce:pure:heap:ffi:unroll
break.py

crashes (same error output as posted earlier in this bug report).

This possibly narrows it down to a bug in the JIT, when applying the unroll
optimisation.  Maybe...
