Segfault & `Error: curl_multi_remove_handle: 8` on 1.10

[mortenpi]

On Julia 1.10.2, we're seeing this segfault. Just before it, we also get this:

┌ Error: curl_multi_remove_handle: 8
└ @ Downloads.Curl /usr/local/julia/share/julia/stdlib/v1.10/Downloads/src/Curl/utils.jl:57

This is the segfault stacktrace:

Unfortunately, I don't have an MWE right now, and the stacktrace doesn't actually say which Downloads call in our code is actually throwing (in expression starting at points to the top-level main() call).
