If you use generate a 32-bit binary using DMD, it generates it in 
a format that the C/C++ extension doesn't understand. You need to 
compile -m32mscoff or -m64, and you need to make sure the /DEBUG 
is passed to the linker, as I don't think dmd passes it that. You 
can do that by passing "-L/DEBUG" to DMD (when using -m32mscoff 
or -m64). There should be a .pdb file that gets generated, when 
you start the debugger it should say that symbols were loaded for 
the exe.

I also can't say for certain if debug information is even 
generated for the unittests, so that might be something worth 
looking into to make sure it does.
