There has been a bit of BIND9 crashing going on lately.

https://bugzilla.samba.org/show_bug.cgi?id=15643
https://bugzilla.samba.org/show_bug.cgi?id=15652

One of the reporters says "building bind against heimdal instead of MIT krb5
solves this issue", which I guess is consistent with a symbol clash.

And yes, a backtrace will help.
