Added new test, It passed. What's your code to use?

Test: https://github.com/icyleaf/halite/blob/master/spec/halite_spec.cr#L14

Result: https://circleci.com/gh/icyleaf/halite/96

I'm using crystal master , not 0.23.1 , this error started when I switched so it might happen only with latest crystal master .

This means that when 0.24 will be out this issue will also happen , so better we try and tackle now ?

It works, please update to HEAD version.
