I mean the currently code is badly broken. The bug is that sometimes, when a string is resized (which doesn't make sense, strings are immutable, right? :-D), the cached UTF-8 string can become corrupted (old pointer not updated). It occurs if * the string is resized (ex: "s += s2") * the string has a cached UTF-8 byte string (ex: int(s) was called before the resize) * the resize moves the memory block to a new address Ok, it's probably unlikely to get these 3 conditions, but from my point of view, it's a major bug because it's in a Python fundamental type (str), it's not a bug in user code and it cannot be worked around (easily). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue25709> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
