[ruby-core:25679] Ruby 1.9 pack('m') and unpack('m') not round tripping

Hello all,

Ruby 1.8.x can round trip a binary file with pack and unpack to
base64.  Ruby 1.9 returns false.  Not sure why, googling and reading
books leads me to believe this should be true in every version, can
any shed some light on this?

Ruby 1.8.6
> data = File.read('spec/fixtures/attachments/test.png')
> data == [data].pack( 'm' ).unpack( 'm' )[0]
=> true

Ruby 1.8.7-p174
> data = File.read('spec/fixtures/attachments/test.png')
> data == [data].pack( 'm' ).unpack( 'm' )[0]
=> true

Ruby 1.9.1-p129
> data = File.read('spec/fixtures/attachments/test.png')
> data == [data].pack( 'm' ).unpack( 'm' )[0]
=> false
