Changeset 0027981: BRepExtrema_DistShapeShape returns not null distance on interfered shapes

The reason of the bug is bad start points on surfaces, which are used by searching roots algorithm as start points for iteration process. Starting with these points algorithm for searching roots of set of equations cannot reach correct root. To find correct start points increasing number of sampling points is applied.
