We make SSL3 disappear to newly built dependencies, the test_ssl success. Refer 
to the modification of OpenSSL on fedoras (address: 
https://src.fedoraproject.org/rpms/openssl/tree/f34 ）

```
 rm -f $RPM_BUILD_ROOT%{_sysconfdir}/pki/tls/*.dist

Christian Heimes  added the comment:

You are using a OpenSSL build with custom, additional patches and your code is 
crashing somewhere in OpenSSL. It is likely that your patches are causing 
issue. I'm not going to provide free service for custom builds.

I want to know whether this is an OpenSSL problem or a python 3 problem, and 
how to fix it? Thanks.
(The OpenSSL source package is large and has not been uploaded successfully. We

[issue44598] test_constructor (test.test_ssl.ContextTests) ... Fatal Python error: Segmentation fault

[tongxiaoge]

tongxiaoge  added the comment:

I installed OpenSSL version 1.1.1l and tested it again. The problem 
disappeared. It should be the reason why the OpenSSL version I used before is 
too low. The current issue is closed

[tongxiaoge]

tongxiaoge  added the comment:

I'm sorry I haven't replied for a long time. I found that the OpenSSL version I 
use is 1.1.1f, which is probably caused by this. Today, I tried to upgrade 
Python 3 to 3.8.12, and the same problem occurred. I'll try again after 
upgrading the OpenSSL version tomorrow. If there are still problems, I'll give 
a reply at that time.

[Christian Heimes]

Christian Heimes  added the comment:

Python 3.9.5 and OpenSSL 1.1.1f are both outdated. Can you reproduce the 
problem with 3.9.6 and 1.1.1k?

Can you tel us more about your system (distribution, CPU arch, compiler) and 
provide a C stacktrace with debug symbols?
