Why? Why is this a problem echoing from CI when it's not a problem echoing the identical data from PHP/mysql?

Because your "pure PHP/mysql" script either doesn't send custom headers or sends them at its very start, while CodeIgniter will send headers
after your controller code is executed.
This also answers your other question:

It's difficult to see how something like this could be the problem, since it's happening consistently with several separate files.[/quote]
I don't know why you're not seeing any error_messages though, unless you've set your environment to 'production'.
