This fixes a bug introduced with the dynamic-array branch. The new version of db_get_field() was using the dbr_size_n() macro to calculate the offset to the start of the buffer area to be zeroed, but when nRequest is zero this gives the wrong result; the dbr_ structures always contain at least one value element, and dbr_size_n() thus has to include that in its size calculation.
