Hi, J.,

I have tested your models. At first, I came across the same assertion! Then,
I examined your model and did some modification, Finally, succeed.

1 The models you provide probably trigger some of the restrictions of
MinkowskiSum. 
 (S29.3
http://www.cgal.org/Manual/latest/doc_html/cgal_manual/Minkowski_sum_3/Chapter_main.html)
I converted the model to the triangle based OBJ model using 3dsmax and there
is no assertion appeared any more.

2 The l_shape is too small to produce any results after "erosion". I scaled
the original model by 4 times (or 5) and get the result as attached.

(Carelessly, I translated the coordinates of the original model. Please try
with the new models)
