Antoine Pitrou <pit...@free.fr> added the comment: Here is a patch. The idea is to use unsigned arithmetic instead of signed, and to check for overflows by comparing with PY_SSIZE_T_MAX.
(the exact reason of the crash is unknown, it looks like either a compiler bug or a mis-optimization as (i < 0) returns 0 while i is -0x7FFFFFFF) ---------- keywords: +patch stage: -> patch review Added file: http://bugs.python.org/file12724/issue4935.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue4935> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
