[3.14] Parser stack overflow on musllinux x86_64 #137231
Description
Activity
this seems to only happen in the context of a pytest session: python -c "import yt"
This may mean this is an issue with
pytest, it is difficult to deduce without a specific minimal reproducer.Thanks for pointing this out !
it might take some time before I can confirm the fix works for us, but it looks very promising. I'll do my best to actually run the check before 3.14.0rc2 . Does anyone mind if we keep this issue open until then ?it might take some time before I can confirm the fix works for us, but it looks very promising.

The fix is currently scheduled for inclusion in 3.14.0 but RM can include it in 3.14.rc2 as it affects yt and scipy on 3.14, leaving it for @hugovk to decide.
Reacted by Clément Robert- marked [3.14] ensurepip failing on s390x musl linux #133801 as a duplicate of this issue
on Jul 30, 2025 I've been trying to reproduce the crash with
docker(using the same imagecibuildwheelruns), but so far I haven't been sucessful: the test session completes without error, so I'm not yet ready to try out the patch, as I except no difference. I'll try to think of a more faithful approach if I can.Adding the label so that we remember to consider this before 3.14.0 candidate 2.

Bug report
Bug description:
When trying to build and test wheels for
yton 3.14.0rc1, we encounter a single error, only on themusllinuximage fromcibuildwheel, which crashes on import withexample logs:

To make things worse, this seems to only happen in the context of a pytest session:
python -c "import yt"completes without raising.A minimal reproducer would necessarily still include a significant amount of complexity, so before I try to reduce it, I'd like to ask:
is it expected that the threshold for triggering this exception may depend on the platform and/or the exact Python version ? is it expected that the threshold may be lower in Python 3.14 than it was in 3.13 ?
