# Different behavior of GeomFill_BSplineCurves algorithm in DEBUG and RELEASE mode
#################################################

#Indeed, the input data are invalid here:
#1. Algorithm requires B-Spline with 4+ poles. Source curves contains two pole only.
#2. Four curves must comprise closed region. But it is not here.
#Therefore, the normal behavior is to throw an exception.
