What is the output of:

exim -d-all+acl --version

If you use `exim -bpru` to pick a message-id to try to deliver, what do
you see around the time of the failure in output of:

exim -d+exec+transport+tls+auth -M $that_message_id

What's the output of:

ldd -a -v $(which exim)

?

Is there anything in dmesg about a delivery attempt failing?

The above error seems to be saying that the delivery process died
without reporting back status. So I tentatively suspect a crash either
in whatever (if any) authentication you perform against the remote
system, or TLS setup. Thus I suspect something like "built with OpenSSL
headers for one version of OpenSSL but using a different version at
runtime".
