That doesn't actually tell us what version of Exim. "exim -bV" will.
Have you raised a Debian bug?

Not much to go on there apart from "it crashed". What was it doing
at the time? Anything logged immediately before? If not, if you place
a custom log line in the connect ACL, does it shoe up consistently
before crashes?

Can you run with debug?
Can you get a coredump (note: Exim is usually run suid)?
