pry(Knapsack::Presenter)> seconds

time = Time.at(seconds).gmtime.strftime('%Hh %Mm %Ss') gives me error

gems/knapsack-1.16.0/lib/knapsack/presenter.rb:82: [BUG] Segmentation fault at 0x0000000000004001

I've tested this line on ruby 2.5.0 and 2.5.1 and I cannot reproduce it. The test suite for knapsack gem is green for both ruby versions.

ruby-2.5.0
$ irb
2.5.0 :001 > seconds=700.0878098011017
 => 700.0878098011017
2.5.0 :002 >  time = Time.at(seconds).gmtime.strftime('%Hh %Mm %Ss')
 => "00h 11m 40s"

ruby-2.5.1
$ irb
2.5.1 :001 > seconds=700.0878098011017
 => 700.0878098011017
2.5.1 :002 > time = Time.at(seconds).gmtime.strftime('%Hh %Mm %Ss')
 => "00h 11m 40s"

What system do you use? Can you try to reinstall ruby?

You may want to try https://knapsackpro.com with Queue Mode to dynamically allocate tests across parallel CI nodes to solve a few problems. More examples here https://youtu.be/hUEB1XDKEFY

You know, I've figured it out (hacked) by removing gem "math" from the Bundle. I don't know what was the reason, but when I include "math" gem into 2.5.0 I'm getting the issue ^^.
Thanks.
