That text has nothing to do with the exit code (the "null 0"). It
comes from a printf() statement in the code that prints out the value
of the null pointer as an integer (which will always be 0).
Hmm, I just realized that any output probably makes exim consider the
delivery to have failed, but since you still get the seg fault message
I don't think that is relevant.
Try using a shell script like this instead then (untested) :
#!/bin/sh
# do this as if we really were sending the input (message) to cyrdeliver
cat | crash -segv
ECODE=$?
# determine what exit code we really want to give to exim
if [ $ECODE == 139 ] ; then
# temporary error
exit 75 ;
fi
exit $ECODE

Religion that God our Father accepts as pure and faultless is this: to
look after orphans and widows in their distress and to keep oneself from
being polluted by the world.
