Description
Buildbot https://buildbot.python.org/all/#/builders/435 has been failing test_gdb with errors like these:

It last succeeded on commit 373bca0 and first failed on fcd5fb4, suggesting that the culprit is one of these commits:
- fcd5fb4 Comprehension inlining: Bug if comprehension contains a lambda #104357: fix inlined comprehensions that close over iteration var (gh-104357: fix inlined comprehensions that close over iteration var #104368)
- 94f30c7 [pathlib] Option so that OSError does not block glob in pathlib library #90208: Suppress OSError exceptions from
pathlib.Path.glob()(GH-90208: Suppress OSError exceptions frompathlib.Path.glob()#104141)
Neither looks likely to affect test_gdb though.
