emile - disable warnings when they are wrong ifor new buffers

emile in these 2 cases allocates an empty uninitilised buffer that
will then be filled - gcc thinks we're passing uninit data to a func -
which is right but intended as it is later filled. disable this
warning for these segments of code.
