Subject: [ruby-dev:31738] integer overflow in Array#fill

こんばんは  sheepman です。

Array#fill でも integer overflow が起きます。

$ cat integer_overflow.rb
a = [0, 1, 2, 3]
a.fill(10, 1, 2**31-1)
p a

a = [0, 1, 2, 3]
a.fill(10, 1, 5)
p a

$ ruby-1.8 -v integer_overflow.rb
ruby 1.8.6 (2007-09-01 patchlevel 5000) [i686-linux]
[0, 1, 2, 3]
[0, 10, 10, 10, 10, 10]
