This issue on bugzilla hasn't been updated since July 2011, but
it's assigned to Sean Kelly:
I've found these threads concerning a precise GC:
Is this issue obsolete, or is it being worked on?
Reason being, I'm writing a game in D and I plan to write it in
nearly 100% D (with the exception being OpenGL libraries and the
like), but I know I'll run into problems with the GC eventually.
If this is an active project that may get finished in the
relative near term (less than a year), then I'd feel comfortable
knowing that eventually problems may go away.
I want to eventually make this work with ARM (Raspberry PI &
cubieboard), and the GC is a major blocker here (well, and a
cross-compiler, but I'll work that out when I get there).
I'm using dmd atm if that matters.
