    Summary: MsQueue and SegQueue suffer from double-free

    Details: Even if an element is popped from a queue, crossbeam would run its destructor inside the epoch-based garbage collector. This is a source of double frees. The flaw was corrected by wrapping elements inside queues in a `ManuallyDrop`. Thanks to [@c0gent](https://github.com/c0gent) for reporting the issue.
