The features_struct.size variable is used to hold a buffer size and it
is also passed in as the size parameter to read(). It should be a size_t
instead of an int.

This patch also changes the size parameter of load_features_dir() to a
size_t to match the same parameter of load_features_file() as well as
the features_struct.size change described above.
