The problem seems in either libgit2 or cargo itself, if you opened one for cargo this can be marked as duplicated of it.
This seems to be a more general problem: I get exactly the same git2 and libgit2 link errors when emerging media-video/rav1e-0.6.5 with lto although my cargo is built non-lto. Any news on this error?
(In reply to Klaus Kusche from comment #4) > when emerging media-video/rav1e-0.6.5 with lto Emerging rav1e non-lto works, the link errors are gone.
Apparently fixed by cargo.eclass, cannot reproduce anymore.
Yes, current version of cargo-c also works here.
