----------------------------------------
I get a ruby crash when running metric_fu on a ~20k LOC ruby on rails app.
The crash happens in the `rails_best_practices` metric, but only when running multiple metrics (using `metric_fu -r`, which runs all).
It does not happen when running only a subset of metrics that includes `rails_best_practices`.
I have not been able to narrow it down further, but it seems that the crash originates in ext/ripper.
