> There was \r\n at the end of every word in the array. I was using chomp and I should have been using something like $_ =~ s/\r[\n]*//; to remove it.

Please note that chomp depends on $/, which is "\n" by default.

But chomp's understanding of a so called logical "\n" is adjusted to the current OS.

So because you were running the same data thru different OS, the "\r" wasn't always caught.

Hence setting local $/ = "\x0D\x0A"; before chomping should solve your issue too.°

°) updated explicit "\x0D\x0A" because this logical "\n" is too confusing
