Hmm, okay. That analysis and fix look good to me. (It looks like none
of the RHEL animals are testing with Curl yet, and locally I was using
Rocky 9...)

I'll work up a patch to send through the CI. I can't currently test
RHEL8 easily -- Rocky 8 is incompatible with my Macbook? -- which I
will need to rectify eventually, but I can't this week.

Thanks!
