For all the apparent ‘l33tness’ the rcov tool is in a pretty sad state. Unusable, even. I get bus errors all the time and I know from experience I am not the only one. Why was this a good tool to use?

vendor/rails/actionpack/lib/action_controller/routing/route.rb:31: [BUG] Bus Error
ruby 1.8.6 (2008-03-03) [universal-darwin9.0]

Purty ain’t it?
