--- Comment #1 from Tobias Burnus <burnus at gcc dot gnu.org> ---

Namely:
"If a list item in a map clause is an associated pointer and
 the pointer is not the base pointer of another list item in
 a map clause on the same construct, then it is treated as if
 its pointer target is implicitly mapped in the same clause.
 For the purposes of the map clause, the mapped pointer
 target is treated as if its base pointer is the associated pointer."=
