Compiling phobos with -cov

[Don Clugston]

Has anyone had any success in compiling phobos with -cov -unittest?
Using DMD 0.161 - Windows, it compiles without warnings, but running the 
executable just prints:

C:\dmd\src\phobos>dmd -cov -unittest unittest
c:\dmd\bin\..\..\dm\bin\link.exe unittest,,,user32+kernel32/noi;

C:\dmd\src\phobos>unittest
Error: circular initialization dependency with module object


Am I doing something wrong?
(I copied my phobos.lib into dmd\lib to overwrite the existing one).
