RSpec output contains ridiculously excessive line returns

I don’t know where else to send this, or I wouldn’t bother the general
Ruby list with it.

RCov is outputting really weird markup on my computer:

Snippet:

C0
code
coverage
information

I’m using the standard Spec::Rake::SpecTask#new method to create a
rcov rake task, and running said task - here’s my rake task:

t.spec_opts = [“–format”, “specdoc”, “–colour”]
t.spec_files = Dir[‘spec/**/*_spec.rb’].sort
t.libs = [‘lib’]
t.rcov = true
t.rcov_dir = ‘meta’ / ‘coverage’

More confusing yet, it works the ‘normal’ way - i.e., I create a
runner file like this:

require ‘rubygems’
require ‘spec’
Dir.glob(‘test/**/*_spec.rb’).each do |f|
load f.gsub(/.rb$/, ‘’)
end

And then run something like this, and it generates clean normal RCov
HTML output:

rcov --text-summary -Ilib --html spec/runner.rb

It’s happening on my friend’s computer as well, so it’s not a local
problem - I’d really like help debugging this, RCov is a very central
tool in my development process >,>
