Actually, this can't be fixed without modifying C API methods PyArg_ParseTuple
and PyArg_ParseTupleAndKeywords, because it's possible to make an object
deallocated before PyArg_ParseTuple returns, so Py_INCREF immediately after
parsing

This patch still assumes that if so-table didn't change then the table wasn't
reallocated (see http://en.wikipedia.org/wiki/ABA_problem). One solution is to
check that so-mask didn't change as well. Also, checking that refcnt 1

I saw that and agree it would make a tighter check, but haven't convinced
myself that it is necessary.
Without this check, it is possible that the comparison shrinks

This code crashes python by using another bug in set_repr. This only affects
py3k. This code relies on out-of-memory condition, so run it like:
$ (ulimit -v 65536 python3 test.py)
Otherwise, it will eat all your free memory before

-1 on special-casing string without an encoding. Current code does (almost)
this:

I've found more unsafe code in Objects/setobject.c.
This code makes Python 3.1.2 segfault by using a bug in function set_merge:
class bad:
def __eq__(self, other):
if be_bad:
set2.clear
New submission from Eugene Kapun abacabadabac...@gmail.com:
This code shows that frozensets aren't really immutable. The same frozenset is
printed twice, with different content. Buggy functions are set_contains,
set_remove and set_discard, all in Objects/setobject.c

Not really, chars are not ints
Yes, however, empty string contains exactly zero chars.
and anyway the empty string fall in the first case.
Strings aren't mentioned in documentation of bytearray slice assignment.
However, I think

__doc__ of bytearray says:
