It's in the middle of some mod_perl scripts, but it's the renderer so nothing should be output before and with that exit() i assure that nothing is output after the print.

It's unix, I'm on ubuntu but it's also showing in BSD, so it must be something gone wrong in the script. With over 10k lines, I'd rather think of a way to fix it there right now.

I know windows sometimes mangles your LFs to CRLFs. The file is not really the matter, as printing an empty string gets the LF there too. I'm thinking more of a record separator or something but I got debugger's block!
