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.
