The Blended model is segfaulting

[Zeitsperre]

Setup Information

• Raven version: v3.8.1
• Operating System: Linux and macOS

Description

It seems that the same type of Segfault being experienced in #35 is being reported in tests that depend on the "Blended" model. Tests around this model have been deactivated for this version of RavenHydroFramework in RavenPy.

Steps To Reproduce

This test (in RavenPy):

def test_ravenpy_blended(self):
    """Test for Blended ravenpy model"""
    model_name = "Blended"
    parameters = [
        0.029,
        2.21,
        2.16,

        0.747,
    ]

    rpm = RavenpyModel(
        model_name=model_name,
        parameters=parameters,
        drainage_area=self.drainage_area,
        elevation=self.elevation,
        latitude=self.latitude,
        longitude=self.longitude,
        start_date=self.start_date,
        end_date=self.end_date,
        qobs_path=self.qobs_path,
        alt_names_flow=self.alt_names_flow,
        meteo_file=self.meteo_file,
        data_type=self.data_type,
        alt_names_meteo=self.alt_names_meteo,
        meteo_station_properties=self.meteo_station_properties,
        rain_snow_fraction=self.rain_snow_fraction,
        evaporation=self.evaporation,
    )
    rpm.run()

Provides this stdout:
