I agree. But I'm not sure how to proceed here. I guess I'll have to set
up a simulation that does an ident call to that host. I've put this on
my list to investigate - thanks for the report.

If you want to do debugging yourself, the relevant part of the source is
the function verify_get_ident() in the module verify.c. To narrow down
where the segfault is occurring, additional debug_printf() statements
can be addded.
