Fast fix for now would be running apt-get install libexpat1=2.2.9-1build1 libexpat1-dev=2.2.9-1build1, The bug originates from libexpat

Thanks for the analysis.
I was just able to reproduce this on Ubuntu 21.10 which has libexpat1 version 2.4.1-2ubuntu0.1 installed.

$ python3 -c 'import xmltodict; print(xmltodict.parse("<?xml version=\"1.0\" encoding=\"UTF-8\"?><rss xmlns:geo=\"http://www.w3.org/2003/01/geo/wgs84_pos#\" version=\"2.0\"><channel><item><title>Title 1</title></item></channel></rss>", process_namespaces=True))'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/home/malte/.local/lib/python3.9/site-packages/xmltodict.py", line 327, in parse
    parser.Parse(xml_input, True)
xml.parsers.expat.ExpatError: out of memory: line 1, column 0

And, after adding namespace_separator=" ":

$ python3 -c 'import xmltodict; print(xmltodict.parse("<?xml version=\"1.0\" encoding=\"UTF-8\"?><rss xmlns:geo=\"http://www.w3.org/2003/01/geo/wgs84_pos#\" version=\"2.0\"><channel><item><title>Title 1</title></item></channel></rss>", process_namespaces=True, namespace_separator=" "))'
OrderedDict([('rss', OrderedDict([('@version', '2.0'), ('@xmlns', OrderedDict([('geo', 'http://www.w3.org/2003/01/geo/wgs84_pos#')])), ('channel', OrderedDict([('item', OrderedDict([('title', 'Title 1')]))]))]))])

It seems that a new change in the libexpat library will fix this issue, planned for version 2.4.7: libexpat/libexpat#577

[kennedyshead]

Closing, seems to be solved
