not a crash, it's an abort but same thing here, also with 4.2.3P2. I've
been unable to find the root cause yet. dhcpd is running for some
seconds and dies the error. Removing the lease file will keep it up a
bit longer:

../../../lib/isc/heap.c:241: REQUIRE(index >= 1 && index <= heap->last)
failed, back trace
