Crash in python bindings and TiGL 3.2.0

[joergbrech]

The following code crashes both on Windows and Linux (with this CPACS file, though it would likely cras with any other CPACS file that has wing guide curves defined):

import os

from OCC.Extend.TopologyUtils import TopologyExplorer
from OCC.Core.TopoDS import topods
from OCC.Core.BRep import BRep_Tool_Curve
from OCC.Core.GeomConvert import geomconvert_CurveToBSplineCurve

from tixi3 import tixi3wrapper
from tigl3 import tigl3wrapper, surface_factories, configuration
from tigl3.geometry import CWireToCurve
from tigl3.occ_helpers.topology import iter_edges

tixi_h = tixi3wrapper.Tixi3()
tigl_h = tigl3wrapper.Tigl3()

dir_path = os.path.dirname(os.path.realpath(__file__))
tixi_h.open(dir_path + "/D150_8_guides_8_profiles.xml")
tigl_h.open(tixi_h, "")

# get the configuration manager
mgr = configuration.CCPACSConfigurationManager_get_instance()

# get the CPACS configuration, defined by the tigl handle
# we need to access the underlying tigl handle (that is used in the C/C++ API)
config = mgr.get_configuration(tigl_h._handle.value)

# get the wing
wing = config.get_wing(1)
Nsegments = wing.get_segment_count()

# get profile wires
profileWire_list = []
for i in range(1, Nsegments+1):
    segment = wing.get_segment(i)
    profileWire_list.append(segment.get_inner_wire())
profileWire_list.append(wing.get_segment(Nsegments).get_outer_wire())

prof_splines_1 = []
for w in profileWire_list:
    e = list(iter_edges(w))
    curve, _, _ = BRep_Tool_Curve(e[0])
    curve = geomconvert_CurveToBSplineCurve(curve)
    prof_splines_1.append(curve)

# Get Guide Curve wires
guideCurve_list = []
guideCurveWire_list = []
guide_curves = wing.get_guide_curve_wires()
t = TopologyExplorer(guide_curves)
for iwire in t.wires():
    guideCurve_list.append(CWireToCurve(topods.Wire(iwire)).curve())
    guideCurveWire_list.append(iwire)

# interpolate profiles and guides
wing_loft = surface_factories.interpolate_curve_network(prof_splines_1, guideCurve_list, 1e-4)

Output:
