in thread Bizarre Perl behavior?

sounds like you are printing control code characters which are messing with the terminal. Like a CR without LF might overwrite the same line over and over again.

You guessed it correctly! 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.

Thanks for the help!

    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
