Latest Debian Buster ppc64le, bind9 keeps crashing every few days with an assert:

named[412]: ../../../lib/dns/rbtdb.c:10330: INSIST(((void *)((header)->link.prev) != (void *)(-1))) failed, back trace

named[412]: exiting (due to assertion failure)
systemd[1]: bind9.service: Main process exited, code=killed, status=6/ABRT
systemd[1]: bind9.service: Failed with result 'signal'.

This appeared after an upgrade from Stretch; the old bind version was not affected.

Hi,

there’s not enough information to go on and the Debian buster has now been switched to
LTS, so I am just closing the bug.  If the issue can be reproduced with current Debian stable,
we will need more than incomplete backtrace (core with full symbols as a bare minimum,
ideally a reproducer).
