We've just rolled out a new box and we're getting core dumps from exim
4.68 on Solaris 10 x86 (two in 24 hours, so its not like its all the
time) - I'm 99% certain this is the problem:

-if (hosts->h_name[0] == 0 || hosts->h_name[0] == '.')
+if (hosts->h_name == NULL || hosts->h_name[0] == 0 || hosts->h_name[0] == '.')
   {
   HDEBUG(D_host_lookup) debug_printf("IP address lookup yielded an
empty name: "
     "treated as non-existent host name\n");


But I've not tested it yet as I can't for the life of me work out in
what circumstances that situation should occur (and my x86 stack
tracing isn't up to the job...)
