Hi,
I would like to ask your guidance as I'm entirely sure whether the problem I'm
experiencing should be posted in CPython's repo as a bug issue.
I've tried using newly released Python 3.11 interpreter in some of my projects and one of
them failed to start with "RuntimeError: invalid SRE code" error.
Looking into implementation of one of the dependencies I've found out that the
issue has been found out by a maintainer and fixed
(https://github.com/pydicom/pydicom/issues/1658).
It looks like this particular regexp caused the `re.compile()` method to raise:
```
re.compile(
r"(?P<h>^([01][0-9]|2[0-3]))"
r"((?P<m>([0-5][0-9]))?"
r"(?(5)(?P<s>([0-5][0-9]|60))?)"
r"(?(7)(\.(?P<ms>([0-9]{1,6})?))?))$"
)
```
I've checked and this hasn't been an issue in all previous Python interpreter
versions, starting from 3.6 (the oldest I've checked).
What's more the regex i correctly recognized and does not cause any issues in
other regexp implementations, e.g. the online tool https://regex101.com/
Could somebody help me decide whether this is indeed a bug?
Yes, it is a bug, and I have found its cause. Please open an issue on
the CPython bug tracker.
