Description
I did this
We're upgrading Homebrew's version of curl to 8.10.0. When testing dependents, we found this error from julia:

Complete logs are available here. The referenced error starts here on macOS 14 arm64.
I am unsure if the problem is in curl or in julia, but it seems like the segfault is happening inside Curl_hash_pick.
I expected the following
No segfault. The segfault doesn't occur with curl 8.9.1.

But note that this occurs on multiple other versions of macOS (macOS 12, 13, and 14 on both Intel and ARM64). We haven't yet been able to verify that this happens on Linux, but I will check this later.
