Bug: compatibility with http-parser 2.9.3 and libgit2 0.99.0-2

[Nagefire]

I'm running julia-latest from on arch linux and I recently updated libgit2 from version 0.28.3 to 0.99.0-2 but now every time I attempt to install or update packages, the package REPL throws

ERROR: failed to clone from https://github.com/JuliaRegistries/General.git, error: GitError(Code:ERROR, Class:Invalid
, invalid version 0 on git_proxy_options)

before this error was ocurring, julia was causing a segfault attempting to install or update packages, the stack trace looked like this:

My julia version info is

To reproduce, install libgit2 0.99.0-2 and http-parse 2.9.3 and attempt to install or update any package.

We only support the versions that Julia ships with. Good to have this issue though.

Is there any workaround/fix for this short of downgrading libgit2 until Julia ships with a newer version?

I believe the problem is that it is not using the libgit2 that is shipped with Julia, but instead built against system libgit2. The issue is tracked here: https://bugs.archlinux.org/task/65540?string=julia&project=5&type%5B0%5D=&sev%5B0%5D=&pri%5B0%5D=&due%5B0%5D=&reported%5B0%5D=&cat%5B0%5D=&status%5B0%5D=open&percent%5B0%5D=&opened=&dev=&closed=&duedatefrom=&duedateto=&changedfrom=&changedto=&openedfrom=&openedto=&closedfrom=&closedto=

Suggested fix for LibGit2 0.99.0: #35232.

For those who end up here after google'ing the error: Downgrading libgit2 (1:0.99.0-3 => 1:0.28.4-1) seems to be a hacky band-aid quick fix.
