Selftests sometimes fail on pypy: TypeError: expected some sort of stmt, but got <_ast.Load object ...> #11771
Description
Example: https://github.com/pytest-dev/pytest/actions/runs/7408595776/job/20157160097
This doesn't always happen, maybe 50% of the time. Started in the last few days. I checked if the PyPy version changed during these days, but seems not (it's 3.8.16).
The error is:

Sometimes it says TypeError: expected some sort of stmt, but got <_ast.Load object at 0x000000000365d040> instead.
