Hahnfeld added a comment.

I just came across an interesting problem...

----------------
I think this assumption may be wrong: The standard defines that each device has an initial data environment (section 1.4.2).

Therefore a `#pragma omp target update` may be a first (and valid) statement which means that it has to be init here as well. Currently the library will in such a case return at this point and ignore the data transfer.
