aisha@ identified a rather recent problem with lang/node, as in the following
would immediately crash (nevermind the node version. It's 100% reproducible
in 7.5 and -current):

$ node
Welcome to Node.js v20.12.2.
Type ".help" for more information.
> require('dns').resolve4('openbsd.org','A',(err, records) => {console.log(records);});

I tracked this back to the following pull request in libcares:

https://github.com/c-ares/c-ares/pull/659

Reverting that fixes things ... diff attached, which includes an update to 1.28.1,
the version I've been testing with.
