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.
