I'm not using the gc-proxy, so I have not hit the problem. My DLL works 
"stand-alone", i.e. it uses the standard GC without sharing between 
DLLs. It loads into a C++/C# environment using COM interfaces (but uses 
http://d.puremagic.com/issues/show_bug.cgi?id=4092 ).

The phobos.dll stuff also just uses the standard GC, exporting the 
symbols to other DLLs to link against. It has been proof of feasibility, 
but I'm not really using it.
