I have the default one created by the Debian package.

See attached file "proc-cpuinfo.txt".

With your instructions I was able to build a static version with debug
symbols. Now, I get a more helpful backtrace at the point where s_client
errors out (see attached file "backtrace.txt").
I have set a breakpoint at e_aes_cbc_hmac_sha1.c:450. The function is called
multiple times before the error occurs and I do not know for what to look
exactly. I have output the parameters of two calls (see attached file "gdb-
output.txt"). Without knowing for what to look exactly, I think it is very
difficult to generate helpful information. Maybe somebody here or on the
openssl-dev mailing list [1] suggests what might be helpful.
Thank you for your support!
Kind regards
Benjamin
