title = "MsQueue and SegQueue suffer from double-free"
description = """
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.
