Looking at the code, I think it's an oversight because objspace->profile.run isn't properly wrapped for a VALUE. So TRUE is returned, which is 1 as a VALUE which equals the value for the Fixnum 0. This changeset should fix the problem: https://gist.github.com/9fe02bd47515cbbcced7 -- http://bugs.ruby-lang.org/
