RSRuby doesn't work with Rails

Though RSRuby gem (and RDS / RData IO modules) work properly on Travis CI within a gem, it faces this error when used with Rails (Passenger / Rack) -

Error: C stack usage  17589078384920 is too close to the limit
Error: C stack usage  17589078384968 is too close to the limit
Error: C stack usage  17589078384872 is too close to the limit
Fatal error: unable to initialize the JIT

Similar issue posted in StackOverFlow and issue tracker of RSRuby gem repo.

However, this small hack seems to make it work.
