Use of Singelton causes with --xrefs, --callsites, --annotate, and --failure-threshold 50 options

[jordandm]

If I use the --xrefs, --callsites, --annotate, or --failure-threshold 50 options, rcov (rcov 0.9.8 2010-02-28) throws an exception and I get the following stack dump:

/Users/jordan/.rvm/gems/ruby-1.8.7-p334@ooyala-web-rails/gems/rcov-0.9.9/bin/rcov:350:in

Can you please add some sample code that can reproduce this? Also, what version of OSX are you running, and what version of gcc?
