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

Research direction
Start by reproducing the Python test code's Delete-then-Save sequence on a loaded SPTAG index, watching the point after tree.bin is written where the segmentation fault occurs. Trace the Delete and Save entry points and verify that the sequence completes without a crash, ideally with a regression test for this case.
