Building library with more than one libraries built with the new -lib switch

[-]

Hi,

the new -lib switch seems to insert these weird object-n (where n is any number) to the libraries and it's causing conflicts if I build more than one library. 

For me the multiple definitions error has always been for:
object-9
	_D8object.912__ModuleInfoZ

I don't know why it's even there. I don't think it's there if make my lib without "dmd -lib" command.

For example: If I have group of independent d source that I build to a lib A.lib (with the -lib switch) and then I have a separate group of d source that I try to build to a lib called B.lib, but it partially depends on A.lib, so I include a.lib in it. Now I get warnings about multiple module definitions. If I build the B.lib without A.lib and then try to build C.lib with A.lib and B.lib I get the same error and when I check the modules with librarian I see that both have the same object-n module in it.
If I compile my sources in A.lib separately and then run librarian explicitly to those files no object-n modules get generated and everything seems to work (meaning my other libraries can be built).
Am I doing something wrong here? 
Or is the new -lib switch even supposed to be used to build more than one lib? 
Maybe it's a bug? 
Has anyone who knows linkers/librarians well tried this?
