Hello Anders,

thanks for your report !. There is an issue of Python 3.6 on Max OS 10.11 where certain ways to declare parameters produce the interpreter crashing. A workarround has been incorporated in order to avoid that condition. Please, pull and compile the code again, to verify the solution.

Enjoy it!
