Most of these look like false positives: we're intentionally making use of C's unsigned arithmetic behaviour. Note that these are technically *not* overflows. As the C standard itself says, in C99 ยง6.2.5, paragraph 9: > A computation involving unsigned operands can never overflow, > because a result that cannot be represented by the resulting > unsigned integer type is reduced modulo the number that is one > greater than the largest value that can be represented by the > resulting type. .. and we're deliberately depending on exactly that well-defined reduction behaviour. Would you be able to do a first pass over the results and identify those that might be genuine issues, worthy of further investigation? ---------- nosy: +mark.dickinson _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46294> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
