Issue #5808 has been updated by jeremyevans0 (Jeremy Evans).
Status changed from Assigned to Closed
The crash reported here was definitely a bug, but it was fixed in Ruby 2.1. It still generates a SystemStackError. I think that behavior is reasonable. If you want a recursion depth check, use `Object#to_json`, not `JSON.dump`. `Object#to_json` has a recursion limit check since at least 1.9.3 (maybe before).
