Sharing data between multiple threads that each use a different instance of the D GC will definitely not work right, because each GC will only know to pause the threads and scan the roots that it has been directly informed of.
There is supposed to only be one instance of the D GC running per process. If you have more than one running then either you aren't linking and loading the DLLs correctly, or you have run into a serious bug in the D tooling.
Or my debugger lied to me.
I have found the gdb debugger on Linux often breaks horribly on my D code, especially when it is multi-threaded, and the debugger is only semi-usable. Maybe the Windows debugger is better now? (I wouldn't know, since I haven't used it in a while.) I think skepticism is warranted here.
