No.

The first case is an array,
    so sizeof(scalar_oid) gives 36 (assuming a 32-bit system),
    and hence  OID_LENGTH gives 9
            (sizeof(scalar_oid)/sizeof(oid))

The second case is a pointer,
    so sizeof(scalar_oid) gives 4 (again, assuming a 32-bit system)
    and hence  OID_LENGTH gives 1
            (sizeof(scalar_oid)/sizeof(oid))

Glad you got things sorted.
