[email protected] changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |RESOLVED CC| |[email protected] Resolution|--- |INVALID --- Comment #1 from [email protected] --- This is intended behaviour. When recurrency function is called with 0, sequence.dropExactly is called with 0ul - 1, which overflows to ulong.max. The code is multiplying the previous factorial ulong.max times. It is not an infinite loop literally, but would presumably take thousands of years to complete. --
