[Pkg-rust-maintainers] Bug#998232: cargo segv when updating crates.io index

Package: cargo
Version: 0.43.1-3~deb10u1
Severity: important
Dear Maintainer,
Since about Oct 12th, we have been seeing cargo on Debian 10
crash with a segv when attempting to update crates.io index
in CI jobs.
This was initially seen inside docker container running CI
pipelines in GitLab, but has been reproduced in regular
VM installs too and by multiple people
Steps to reproduce
$ git clone https://gitlab.com/libvirt/libvirt-rust
$ cd libvirt-rust
$ cargo test
Updating crates.io index
Segmentation fault (core dumped)
This doesn't appear limited to the libvirt-rust project. For
example this also fails
$ git clone https://github.com/enarx/sev
$ cd sev
$ cargo test
Updating crates.io index
Segmentation fault (core dumped)

Suggests the problem is likely related to libgit2 HTTP handling.
