I don't know if this is the intended behaviour, but...

Reproduction steps

Setup the repo with normal git:

git init
echo a > a.txt
git add a.txt
git commit -m "add a"

git symbolic-ref refs/foo refs/heads/master
git symbolic-ref refs/bar refs/heads/master

Compare the references with libgit2:

git_repository *repo;

// open repository somehow, details don't matter here

git_reference *foo;
git_reference *bar;

git_reference_lookup(&foo, repo, "refs/foo");
git_reference_lookup(&bar, repo, "refs/bar");

printf("%d\n", git_reference_cmp(foo, bar));

I am using the library from Rust using git2-rs, apologies if this isn't the exact C code to do it!
It is a relatively simple thing to do though, so I should've got it right I think.

Expected behavior

git_reference_cmp returns a non-zero value (it doesn't matter what, but could be the same as strcmp("refs/foo", "refs/bar")).

Actual behavior

git_reference_cmp returns zero, suggesting that the two references are actually the same.
