I was able to use GDB with debugging symbols to get a stacktrace
at the point of sigfault. Again, this is Exim 4.24 running
under Solaris 7 with GCC 2.95.3 using a command line of:
exim -v -bhc 1.2.3.4
It also dies when running when receiving regular messages via SMTP,
so the crash is not just limited to -bhc mode.
Hope this helps.
