Angel Stall warning during go around

Question;

Is it acceptable to reach the short-time stall warning during automatic go around with one engine inoperative? Should I disengage AP and proceed manual go around?

My answer;

Having flown in turbulent and thermal conditions close to the ground, my
experience tells me that,for a given acceptable IAS and attitude (AOA),the stall warning will trigger when airflow direction changes occur through the start of thermals or the gusting and rolling effects of turbulence close to the ground.
I would think, though,that stall sensors are different from one aircraft type to another and,although I fly low performance power planes,high performance aircraft on auto pilot (or auto anything), may react differently.
Another thing is that with multiengine aircraft, there is a possibility that
differential thrust, causing slipping or skidding, may trigger occasional airflow changes (turbulence) over one wing etc.
IF Airspeed and Attitude are within limits,occasional and intermittend stall warning sounds should be nothing to worry about.
