There was a change in Rails 3 such that calling (for instance) `@blog.posts.new` was exactly identical to calling `@blog.posts.build` - that would explain why this didn't show up on Hobo...

FWIW, it only took a few adjustments (all to code in `spec/`) to get the suite passing on 4.1.8. Will submit a PR when I get a minute.

@lustremedia I've not seen this particular issue. Can you provide more detail on what triggers the stack overflow? In particular, the field name that's causing it?
