No, by PHP itself, actually.

When you create an output buffer using ob_start() and fail to clear it with
an appropriate ob_end_* call, then PHP will flush the output buffer at the
end of script execution.

Notably, this actually happens before any callbacks that were passed to
register_shutdown_function() are called. Shutdown functions don't get the
contents of the output buffer.
