StateManager's delete_state function error

edit

Hi! I worked with EnergyPlus API Python V9-5-0 and all was good. Now, I tried to run the same program with EP API Python V9-6-0 and the function api.state_manager.delete_state(state) present me an error in the lecture of a file. The follow is the messege in the Terminal:

    self.api.stateDelete(state)
OSError: exception: access violation reading 0x0000000000000010

The complete code is very large, but the problem can be see here:

state = api.state_manager.new_state()
api.state_manager.reset_state(state)
api.runtime.callback_begin_zone_timestep_after_init_heat_balance(state, callbackFunction)
api.runtime.run_energyplus(state, ['-d', var_case_n['Folder_Output'], '-w', conf_experimento['Weather_file'], epJSON_file])
api.state_manager.delete_state(state)

Wenn I don't use the function api.state_manager.delete_state(state) all is good, but with the time the memory give me problems. I like to use V9-6-0 because is faster. Somebudy can help me?
