Crash in "host"

Summary

Running "host" with the -C option causes it to crash sometimes. I've observed it on my MacOS Sonoma 14.2.1 laptop, and I've also seen a report by Francisco Obispo of a similar crash on the bind-users mailing list.

What is the current bug behavior?

Sometimes, "host" crashes with this error:
