Martin Panter added the comment: Looking over r60793, the overflow check at Modules/cjkcodecs/multibytecodec.c:836 looks vulnerable to being optimized away, because it can only detect the overflow if the line above has already overflowed. Perhaps change PY_SSIZE_T_MAX to MAXDECPENDING. I wonder if any of the GCC optimization and warning modes can detect this case?
Also, Python/ast.c:3988 checks using PY_SIZE_MAX, but then passes the value to PyBytes_FromStringAndSize(), which expects ssize_t and in the best case would raise SystemError. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue1621> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
