Starting with 2.2.0, error handling has been implemented to gracefully fail when array creation requires more memory than available. This occurs when the range size, or end_num, need arrays greater than the amount of avalable memory. The first case shows the message ERROR1: range size too big for available memory. and the second case ERROR2: end_num too big for available memory.
