On my system, running the simple smtplib Example
from the Documentation results in a segmentation fault.
Execution stops and no mail is submitted.

I debugged into the Python source code, but my
understanding of the inner mechanisms doesn't
suffice to fix the problem.

I update my system periodically using "apt-get update ;
apt-get upgrade". I don't remember, when it was the last
time Python was upgraded.

I made the files availabe:

I cannot reproduce this.

I've tested: 

Python 2.3 (#1, Sep 13 2003, 00:49:11) 
[GCC 3.3 20030304 (Apple Computer, Inc. build 1495)] on darwin
Type "help", "copyright", "credits" or "license" for more information.

Python 2.3.4 (#2, Jul  5 2004, 09:15:05) 
[GCC 3.3.4 (Debian 1:3.3.4-2)] on linux2

Python 2.2.3+ (#1, Jun 20 2004, 13:32:48) 
[GCC 3.3.4 (Debian)] on linux2

The first is the system python on MacOS X, the other two are current 
Debian packages (python2.3 and python2.2) on Debian stable.

Indeed, I did compile python 2.2.1 with Gcc versions 2.95,
3.0 and 3.3. The segfault only occurs in the 2.95 compiled code.

Please, could you verify if this problem persists in Python 2.3.4
or 2.4?

If yes, in which version? Can you provide a test case?

If the problem is solved, from which version?

Note that if you fail to answer in one month, I'll close this bug
as "Won't fix".

Thank you!

I think that's OK.

I just ran into this while using the smtplib example on:

2.6 (r26:66714, Jan 17 2012, 11:02:11)
GCC 4.1.2 20080704 (Red Hat 4.1.2-44)

Running the program simply gives a "Segmentation Fault (core dumped)"

Running it under gdb...

[Thread debugging using libthread_db enabled]
[New Thread 0x2b0257007b80 (LWP 2567)]

Program received signal SIGSEGV, Segmentation fault.

Could you please indicate exactly the command you're running, and provide the full backtrace?
