I can reproduce the problem (not sure it is the same) when not a complete torus is built but only a sector, restricted in both directions, and when angular range by small radius passes over 180 degrees.

In DRAW:

> ptorus p 10 2 90 270 45

The shape is invalid and causes serious problems in display in both axo and AIS viewers

The same problem exists also in OCC6.3.0

My code is like follow:
BRepPrimAPI_MakeTorus aTorus(120, 35, 90);

I am sorry, the BRepPrimAPI_MakeTorus function is right,
the parameter angle's unit is radian not degree.

It's better raise a exception when the angle is greater than
PI * 2.
