Both object file formats, OMF (dmd -m32) - used by Optlink and 
COFF (dmd -m32mscoff and dmd -m64) - used by Visual Studio C++, 
and their respective linkers have different pros and cons.  So 
you have the option to choose between either of them with DMD. 
Since COFF support was added after OMF historically it was the 
more unstable of the two, AFAIK. It just happens that for this 
particular case it is the better option, or at least will be 
until this bug is fixed. Also, since Optlink is bundled with the 
DMD installation, and VS is a separate large download, Dub users 
are more likely to only have Optlink, which is why its the 
default one.
