SaveIndex failed (Segmentation Fault) after Delete. #78

Describe the bug When I test SPTAG in python by your python test code. I find when I delete some data from Index, SaveIndex always get segmentation fault.

This is Delete and Save code:

def testDelete(index, x, out):
   i = SPTAG.AnnIndex.Load(index)
   ret = i.Delete(x.tobytes(), x.shape[0])
   print (ret)
   print("Del finished...................")
   i.Save(out)

SPTAG_save_err After save tree.bin finished, segmentation fault. Thanks for your favor.
