Bug ID: 95236
Summary: OMP 'GOMP_MAP_STRUCT': a structure is more than the

..., and the answer (technically) may easily be "yes", considering ABI-mandated
padding, for example.
But: is that user friendly? Consider the test case I'm attaching, where
'struct s' consists of fields 'a', 'b', which both get mapped -- yet, 's'
itself isn't considered to be. At the user level, should a structure equal the
sum of all its fields, or "do we have to be complicated"?
I have not fully thought that through, just noticed this when looking into
something else. I also have not verified OpenMP behavior.
