--- Comment #6 from Nathan Sidwell <nathan at gcc dot gnu.org> ---
The code is ill-formed, for (at least) 3 reasons:
1) only one of the member functions is marked as 'acc routine', before being
called in an offloaded region. the 'pi' function is marked, but the iterator
members, _DummyRed member and the function invoker are not.
2) the loop itself does not contain independent iterations
3) the 'copy(__thread_results[1]...) is copying a single element array, but
then indexing it incorrectly.
Now, openacc doesn't appear to provide any mechanism for marking (say) all the
member fns of a class as routines, and apparently in-class use of 'pragma acc
routine' is not permitted.
Openacc doesn't appear to address non-pod data objects or member functions.
Let alone the complexities of using the STL.
The compiler shouldn't blow up of course ...
