It is fine so long as your beam reference line is on the curve of the slab.

Let me add a bit of explanation to Barry's excellent point.
Curves are approximated by ArchiCAD.
Those segmentations you see in the problematic picture is when the segmentation of the Slab and the segmentation of the Beam are derived from different curves and so there can be such inaccuracies.
When the Beam's Reference Line is on the contour of the Slab, the segmentation of their curved surfaces will be derived from two exact same curves. This is why they give proper result in 3D.
This same principle can be used in similar cases as well, but with other element types. For example a curved Wall and curved Slab on top of it (when the top fo the Wall is at the bottom of the Slab, they don't intersect).
Although, I might add, with AC17 this may be a less of a problem because intersecting elements may be modelled differently in the future.

Is AC17 available?

Not yet. From the press release here:
http://www.graphisoft.com/info/news/press_releases/ac17.html

ArchiCAD 17 will be released on June 1, 2013, with shipment to customers beginning within a few weeks of the official release. Following a tight release schedule, all 26 local versions are planned to reach the market by the end of Q3 2013.

So, "within a "few weeks" for certain languages. I've not seen a published timetable of when each version will be released, but typically the INT, GER, USA and AUS seem to be released first as I recall.
