Summary: The Rcov rake task fails when running the specs

Initial Comment:
If I run the following task with Rake:

desc "Run all specs with RCov"
Spec::Rake::SpecTask.new('spec_rcov') do |t|
  t.spec_files = FileList['spec/**/*spec.rb']
  t.rcov = true
  t.spec_opts = ["-fh > build/spec_results.html"]
end

I get this error:

$ rake spec_rcov --trace

Same error I get if I just run the specs through rcov:

$ rcov spec/**/*spec.rb

........../usr/local/lib/ruby/gems/1.8/gems/activerecord-1.14.4/lib/active_record/callbacks.rb:235: [BUG] Bus Error
ruby 1.8.4 (2005-12-24) [i686-darwin8.8.1]

Abort trap


But I don't get the error if I turn off rcov's optimized C runtime

$ rcov spec/**/*spec.rb --no-rcovrt

....................................

Finished in 12.125441 seconds

36 specifications, 0 failures


I've noticed that if there aren't too many specs then it runs just fine.  Once we pass a certain number we get the error listed above.

We're using:
OS X 10.4.8
1.5 GHz Intel Core Solo
1Gb ram

rcov 0.7.0
rcov rails plugin installed as an external svn repos (so it's on edge)
rspec 0.7.4
rspec rails plugin for 0.7.4
rails 1.1.6
Ruby 1.8.4

Try this instead:

If I run the following task with Rake:

desc "Run all specs with RCov"
Spec::Rake::SpecTask.new('spec_rcov') do |t|
  t.spec_files = FileList['spec/**/*spec.rb']
  t.rcov = true
  t.spec_opts = ["-fh"]
  t.out = "build/spec_results.html"
end

Also see http://rspec.rubyforge.org/rdoc/classes/Spec/Rake/SpecTask.html

Does that work for you? If you still get a BUS error I'd take it up with Mauricio Fernandez (the rcov author)
