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 for reporting the issue.
