The update from libcurl-8.13.0-1.fc43.x86_64 to libcurl-8.14.0~rc1-1.fc43.x86_64 causes cargo to memleak when accessing the Internet.

For more information on how this conclusion is drawn: https://discussion.fedoraproject.org/t/rawhide-anyone-aware-of-why-cargo-has-been-memleaking/154420


Reproducible: Always

Steps to Reproduce:
dnf in -y cargo git wget
wget https://crates.io/api/v1/crates/mise/2025.5.11/download#/mise-2025.5.11.crate
tar xf download
cd mise*/

Expected Results:
It should not memory leak.

Additional Information:
Only reproducible on Fedora Rawhide, not 42, 41, ...

Only reproducible when cargo has Internet access (which is why it works fine with Fedora builders, but not on Terra).

Also reproducible with `%cargo_build` or `%cargo_install` with Internet access.

Setting severity to urgent since a memory leak… crashes computers.
