>From the source:

 * @base_uri: Base URI string
 * @reference_uri: Reference URI string
 * @buffer: Destination buffer URI
 * @length: Length of destination buffer

So it reads @base_uri and @reference_uri and outputs ( writes) to @buffer
which must be pre-allocated to @length bytes.

... although it seems that function doesn't check it.  Oops.

To be safe, you can use a buffer of size
  strlen(base_uri) + strlen(reference_uri) + 1
which is what raptor_new_uri_relative_to_base_counted() uses
