{ Tests passing of different records by value to C methods. 
 One type of these records has one field which is a simple array of bytes,
 the other consists of a few fields of atomic size.
 
 Note that it does not only test a single field of these records, but all
 by comparing the sum of the field values with the sum returned by the
 C function.
