This patch fixes issue with unitialized variable which makes ctypes crash in
error handler.
Note that for you it merely turns "Segmentation fault" into MemoryError
exception. Python ships with buggy version of libffi, which tries to allocate

SMTP.connect method expects _get_socket() method to return socket object:

to create a backtrace in such a deadlock situation
Sorry, I should have mentioned that. In order to get backtrace you let the
process freeze, attach gdb to it (it will freeze to

In the libc case you shouldn't give absolute path in CDLL: CDLL('libc.so.6') is
better. You use "/lib/libc.so.6" path, but Python (and ctypes.so) actually uses
something like "/lib/tls/i686/cmov/libc.so.6" - these are tw

I think the expression "cur + step" in line 2660 of listobject.c (py2.7 trunk)
overflows to negative value and the "if" branch isn't entered.
if (cur + step >= Py_SIZE(self)) {
lim = Py_SIZE(self) - cur - 1;
}

Using "grep" I found the same code in Modules/arraymodule.c:

I attach the patch. I changed signedness in all three sequence types and made

I had odd problems matching line numbers reported by Windows compiler

signedness warnings against Python 2.x r77957:

I wrote a Perl script testing this issue and it fails too, so it's most

It seems most IMAP4 methods accept str as arguments right now (I
checked: list, lsub, myrights, select, status, search, fetch) and
login() is a sole exception. I know the protocol is mostly ascii only,
but still having possibility of using str in the API feels
Marcin Bachry added the comment:
Ok, it think it's good to leave internal _quote() function operating on
bytes and convert password argument in login(). The method now works
with both str and bytes as arguments.

Actually it's a bug in ctypes.util.find_library() which is called from
uuid.py. The function doesn't close() popen object leaving forked

Your diff is better than mine and looks quite similar to patch number 2
in #4470. If the whole #4470 can't be accepted for now, we could at
least apply this one change, because without it SMTP_SSL is totally
unusable. Daniel, maybe we can mark this bug or

Here's a dumbed down version of the test from #4470. It requires

I think there are two bugs spotted here. The first is the mentioned
missing "close" param to _fileobject in makefile() method.
The second one was noticed by Jonathan. He doesn't use makefile() at
all, yet his socket isn't closed either. He
