   similar problem has been spotted, as i tried to execute some code like this:
   **Version 0.11.1**
   
   ```python
   def gen_sym(seq_len):
       data=mx.sym.Variable('data')
       label = mx.sym.Variable('label')  # NT
       output, _ = stack.unroll(seq_len, inputs=data, merge_outputs=False, layout='NT')
       pred = output[seq_len-1]
       pred = mx.sym.reshape(pred, shape=(batch_size,-1))
       pred_e = mx.sym.FullyConnected(data= pred, num_hidden=1)
       sym = mx.sym.broadcast_add(pred_e, label)
       sym = mx.sym.MakeLoss(sym)
       return sym, ('data', ), ('label', )
   ```
   However, if i replace `pred_e` with `pred` in *broadcast_add* it works fine
