gh-94673: More Per-Interpreter Fields for Builtin Static Types by ericsnowcurrently · Pull Request #103912 · python/cpython (original) (raw)
git bisect got me here.
I'm testing Python 3.12 with pybind11 (master @ https://github.com/pybind/pybind11/tree/d72ffb448c58b4ffb08b5ad629bc788646e2d59e).
# first bad commit: [de64e7561680fdc5358001e9488091e75d4174a3] gh-94673: More Per-Interpreter Fields for Builtin Static Types (gh-103912)
I double-checked that this is true:
The gdb backtrace is below. #0 & #1 are pointing here:
Does this ring any bells? Is there something obvious that we need to do differently in pybind11?
Steps to reproduce are involved, roughly:
- gcc (Debian 12.2.0-14) 12.2.0
- install cpython from scratch
- pip install setuptools
- pytest installation from git main branch: python3 setup.py install
- building pybind11 unit tests (succeeds)
- pytest then crashes with a segfault at startup
I can send more details or try to reduce as needed. Please let me know.
