Careful with that - some nuances will turn up that will bite you on the ass. I found out last year that Apache's MD5 module creates different hashes(!) on Windows than it does on UNIX.
If that is true then at least one of them isn't actually generating an MD5 hash.
I'm just guessing, but I bet you were also encoding the line ending characters. That would be encoded differently on Windows and UNIX, so you'd actually be hashing two strings that differed by at least one byte.
