core dumped when reading CDX file downloaded from USPTO

[eloyfelix]

Thanks for fixing #1126. I saw this other issue before but I mistakenly assumed that it would be related...

Steps to Reproduce

Python: 3.11.3
Indigo: 1.12.0.rc1 (pip installed)

>>> from indigo import Indigo
>>> 
>>> indigo = Indigo()
>>> 
>>> for item in indigo.iterateCDXFile("US06837803-20050104-C00001.CDX"):
...     print(item.smiles())
... 
O1CCCC[AlH]1
double free or corruption (out)
Aborted (core dumped)

error if using a buffer to read (what I do since I'm reading from a zipfile)

>>> with open("US06837803-20050104-C00001.CDX", mode="rb") as f:
...     for item in indigo.iterateCDX(indigo.loadBuffer(f.read())):
...         print(item.smiles())
... 
O1CCCC[AlH]1

Expected behavior
Molecules being parsed of failing to parse in a controlled manner.
