RUBY/dl bug ?

[Shashank Date]

I was trying out the RUBY/DL samples which can be downloaded from:
http://ttsky.net/ruby/ruby-dl-sample/win32/
and while trying out the stream.rb example, I got the following error on
Win XP (Home) using ruby one-click install:

Hi Shanko,

I think it's a Ruby bug that was fixed.

* pack.c (num2i32): pack should not raise RangeError.
[ruby-dev:22654]


As a work-around, try changing line 73 in dl/types.rb
from:
proc{|v| [v].pack("l").unpack("L")[0]}],
to:
proc{|v| [v & 0xffffffff].pack("l").unpack("L")[0]}],
