[3.14] gh-139400: Make sure that parent parsers outlive their subparsers in pyexpat (GH-139403) by miss-islington · Pull Request #139606 · python/cpython (original) (raw)

- Modules/pyexpat.c: Disallow collection of in-use parent parsers.
Within libexpat, a parser created via XML_ExternalEntityParserCreate
is relying on its parent parser throughout its entire lifetime.
Prior to this fix, is was possible for the parent parser to be
garbage-collected too early.
(cherry picked from commit 6edb2dd)
