Reduced code from the Examples document
The second case in the code example target_struct_map.4.c provided in the
upcoming OpenMP Examples document leads to a runtime error.
Libomptarget message: explicit extension not allowed: host address specified is
0x00007ffd5c65cf38 (24 bytes), but device allocation maps to host at
0x00007ffd5c65cf48 (8 bytes)
The mapping of S2.p[:n] at the target data construct should only map the array,
but not the pointer S2.p.
The map clause at the target construct should create the struct with elements
a,b,p and perform the pointer attachment for S2.p</pre>
