While we are at it:

lwgeom11=# select multi('GEOMETRYCOLLECTION EMPTY'::geometry);
ERROR:  invalid memory alloc request size 0

I know that it may be nonsense to call multi() on an empty collection,
but this was where it had bitten us as we called multi() on the result
of an intersection() operation.
