Mutiple axes homing in same cycle with one axis squaring stressfree mode crashes FluidNC

[nxperera]

When two axes home in same cycle (e.g. X and Y both has /homing/cycle = 2 ) if one axis is ganged(has two motors) with independent limit switches on each motor and squaring enabled, FluidNC homing crashes and CNC becomes unresponsive . Serial output following

My configuration example

axes:
     x:
      homing:
           cycle: 2
    motor0:
      limit_pos: gpio.33
      hard_limits: false
      pulloff: 2.000

 y:
    homing:
      cycle: 2

    motor0:
      limit_pos: gpio.34
      hard_limits: false
      pulloff: 2.000

    motor1:
      limit_pos: gpio.32
      hard_limits: false
      pulloff: 2.000

This happens because X and Y both are in same homing cycle and Y is squired with independent limit switches which make FluidNC to use squaredStressfree() routine which eventually calls following pulloffOffset() method while homing x axis where _motors[1] is null and that cause the crash.

float Axis::pulloffOffset() { return  _motors[1]->_pulloff - _motors[0]->_pulloff }
