I suspect diotalevi hit the nail on the head in the chatterbox. This is not a bug - in fact the regex is matching what one would expect it to match: you're searching for \n. If you type your script on Unix, line endings are \n, on Windows, they're \r\n. To get things to match correctly, regardless of OS, try using diotalevi's suggestion of first storing whatever is at the end of a line in a variable and putting that variable in the regex, or first normalize your input to either form, e.g.:
my $data=qq(One line two line three line ); $data =~ s/\r\n/\n/; # use your regex. # code is untested
