2) Using these two derived datatypes,
Build another derived datatype with MPI_Type_struct:
advtype: derived from datatype1 and datatype2
- advtype:
- count = 2, blocklens[0] = 1, blocklens[1]=1,

The problem is that the displacement of the second derived datatype(datatype2) which formed the final derived datatype(advtype)

If this bug has been fixed in the previous not-working package, this test will issue a printf message to tell the developer to change
