Subject: [ruby-core:24708] [Bug #1859] Random#int Segfaults with Non-Integer Ranges

Issue #1859 has been updated by Run Paint Run Run.


Thanks, nobu. Could you double check the bounds for a Float..Integer Range? #int(3.1..5) seems to be resolved to #int(3...5):

  >> prng = Random.new(2)
  => #<Random:0x92fd6c8>
  >> 20.times.map { prng.int(3.1..5) }
  => [3, 4, 4, 3, 3, 4, 3, 4, 3, 4, 3, 4, 4, 4, 4, 4, 4, 4, 3, 3]
  >> prng = Random.new(2)
  => #<Random:0x92ee27c>
  >> 20.times.map { prng.int(3..5) }
  => [3, 4, 3, 5, 5, 3, 5, 4, 4, 5, 3, 3, 3, 4, 5, 3, 5, 5, 5, 4]
