I tried this, but exim still segfaults

Sorry, that was very ambiguous. I've compiled and run it successfully
_on another host_ (running RH 7.3). I've never had it running on the
machine it's segfaulting on (fortunately it works on production boxes at
work, the problem is on my desktop at home ;-)
I used strace (last bit of the output below) and it shows that the
segfault happens after the fork, just after libdb3.so.3 is read. Maybe
my initial suspicions were correct ...
All help gratefully received
Thank you
