I haven't found a not stop-the-world thread-safe GC library. So I decided to write one myself a few day ago.
But I am new to Rust and Unsafe Rust. I encountered a bug beyond my ability. It somehow deadlocked on this line https://github.com/tsao-chi/concgc.rs/blob/cd7243821cea13efd5fd1a5d93bae06bcc3ecea7/concgc/src/lib.rs#L798 when I tried to run the test "new_bare_root".
Update: I have fixed this bug.
Are there any other not stop-the-world thread-safe GC libraries?
