Issue #2951 has been updated by Alexandre Riveira.


ruby 1.8.7-p249 is minor of 0 seconds example
start_time = Time.now; ("01001-000".."99990-000").include? ""; puts Time.now - start_time
1.4e-05
=> nil

ruby 1.9.1
/usr/local/ruby-1.9.1-p378/bin/irb
irb(main):001:0> start_time = Time.now; ("01001-000".."99990-000").include? ""; puts Time.now - start_time
80.55897691
=> nil
Because ruby 1.8.7's extremely fast and ruby 1.9.1 is so slow?
This is a bug !
