Not from the information you've provided. Someone might be able to
identify a misconfiguration if they saw the actual zone and named.conf
files.

However even if there is an error in your setup, you have found a
bug. An assertion failure means BIND9 has detected some sort of
internal inconsistency: a mangled data structure, an invalid parameter
to a function call, etc, etc. This is supposed to be something that
"cannot happen". So file a bug report and keep any core dump for
analysis. Fixing the assertion failure will probably mean modifying
the source code and releasing a new BIND9 version. I think you might
prefer the ISC to co-ordinate that.
