X Title: [3.14] gh-151218: Replace sys.flags in PyConfig_Set() (#151402) by vstinner · Pull Request #151553 · python/cpython

Description: PyConfig_Set() and sys.set_int_max_str_digits() now replace sys.flags (create a new object), instead of modifying sys.flags in-place. Modifying sys.flags in-place can lead to data races when multiple threads are reading or writing sys.flags in parallel. Use _Py_atomic functions to get and set max_str_digits members. (cherry picked from commit b16d23f) Issue: gh-151218
