Bug report
A clear and concise description of the bug
Followup to #103968 (comment).
The DeprecationWarning for PyType_Spec in 3.12.0rc1 is emitted on <frozen importlib._bootstrap>:400 which makes it quite difficult to know what package is responsible.
In my particular case I found that, after reading #103968, it might be protobuf.
And indeed that's how I can reproduce it.
# test.py
from google.protobuf import descriptorpip install protobuf==4.24.0
python -X dev test.py<frozen importlib._bootstrap>:400
DeprecationWarning: Using PyType_Spec with metaclasses that have custom tp_new is deprecated and will no longer be allowed in Python 3.14.
To be clear, I don't mind the warning. I'm just wondering if it's possible to improve the error location.
