--- Comment #3 from Phil Pennock <pdp@???> ---
This appears to be new logic introduced with commit `a39bd74d` 2015-03-15:
http://git.exim.org/exim.git/commit/a39bd74d3e942db1b465cae643e1a4766ffb304e

This was introduced to fix bug 1141, "remote_smtp reuse when should not be".

I'm not familiar with this new logic, but at a glance, it looks like the usage
of `deliver_get_sender_address()` is assuming that the previous message from
the same connection is still on disk, but when it's delivered before the next
message from that source, the `-H` file is missing,
`deliver_get_sender_address()` returns `NULL` and things go wrong.

But that doesn't explain why the backtrace shows `tblock=0x0` here, because it
should have done the same on lines 1278/1279 as it does on 1282 and it should
have crashed there.
