実行時エラーのメッセージから、 crossbeam-epochクレート v0.3.1 でエラーが起きていることがわかる。

thread '<unnamed>' panicked at 'attempted to leave type `nodrop::NoDrop<(epoch::Epoch, garbage::Bag)>` uninitialized, 
which is invalid', ... /.cargo/registry/src/github.com-1ecc6299db9ec823/crossbeam-epoch-0.3.1/src/sync/queue.rs:57:28

Cargo.lock で指定されている crossbeam-epoch のバージョンが古いことが関係している。

cargo update を実行すると解決した。

おそらく crossbeam-epoch v0.3.1に既知の問題があり、最近のバージョンでは解決しているのだと思われる。

Windows 10でも同じようにパニックしました。

GitHub上の Cargo.lock をアップデートしておけば、新規にクローンする人については問題ないと思いますので、後は既にクローンしている人向けに正誤表か README.md で事前に cargo update してもらうよう説明を入れておくのがいいのではないかと思いました。
