The problem is with the following check:

    n = digits * bits_per_char + PyLong_SHIFT - 1;
    if (n / bits_per_char < p - start) {
                        "int string too large to convert");

The problem is that n / bits_per_char gives the number of digits required. But p - start has the number of '_'s included in it. So even for valid cases, if the number of '_'s is above a limit, this check holds true and an overflow is raised.

Fix: Replace p - start with the actual number of digits.
