Thanks, Christoph, I stumbled over the same bug also. I was on the edge of compiling openssl from source to get this feature that's already present, only not documented in the man page.
The bug is still present in Jessie and also in Debian's Package: openssl Version: 1.0.2d-1 FWIW: The version over at https://www.openssl.org/docs/manmaster/apps/s_client.html doesn't have this bug. Regards, and thanks. Andreas
