           Summary: std.concurrency: destructors called twice on objects
                    passed as Message
           Product: D
           Version: D2
          Hardware: x86
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P1
         Component: phobos

          Reporter: r.sagitario at gmx.de

I don't have a reduced repro case, but the unittests for std.concurrency
crashed for me on Win32 when enabling the precise GC in
https://github.com/dlang/druntime/pull/1603.

This is caused by the destructor of a Variant being called twice when a Node of
the Message List is reused by the MessageBox.
