$ python -X int_max_str_digitsFatal Python error: config_init_int_max_str_digits: -X int_max_str_digits: invalid limit; must be >= 640 or 0 for unlimited.Python runtime state: preinitializedBut if PYTHONINTMAXSTRDIGITS environment variable is defined, the invalid option is no longer rejected:
$ PYTHONINTMAXSTRDIGITS=5000 python -X int_max_str_digitsPython 3.12.0a0 (heads/main:e37ac5fbb6, Sep 15 2022, 15:03:41) [GCC 12.2.1 20220819 (Red Hat 12.2.1-1)] on linuxType "help", "copyright", "credits" or "license" for more information.>>>It's just because thevalid variable in config_init_int_max_str_digits() is not initialized again in the -X option code path, after the env var is parsed.
