ok

According to @encukou, the failure started to occur after a system update:

OpenSSL 3.3.0→3.4.0
Linux 5.15.0→6.8.0
glibc 2.39→2.40
GCC 13.2.1→14.2.1
etc.

Failing tests:

test_stls (test.test_poplib.TestPOP3Class.test_stls)
test_stls_context (test.test_poplib.TestPOP3Class.test_stls_context)

stls stands for "Start a TLS session":

    def stls(self, context=None):
        """Start a TLS session on the active connection as specified in RFC 2595.

                context - a ssl.SSLContext
        """

First failure: https://buildbot.python.org/#/builders/484/builds/6224

That's AMD64 Arch Linux TraceRefs 3.x. test_poplib is also failing on AMD64 Arch Linux Asan 3.x, first failure: https://buildbot.python.org/#/builders/582/builds/6182

Are there changes/additions in the OpenSSL 3.4.x branch to its error codes that require updating our header files (see https://github.com/python/cpython/blob/main/Tools/ssl/make_ssl_data.py)?

Thanks for the pointer, @ned-deily! Here's where it led me: #127331

Oh! The [SYS] library means that the error code is a system errno and the message should be retrieved using perror rather than ERR_reason_error_string.

I wonder if this should raise an OSError using PyErr_SetFromErrno, rather than a SSLError.

The failure is an EPIPE, raised when the server is shutting down:

Fatal Python error: Aborted
