It doesn't, you should add it to the GC with GC.addRoot or 
GC.addRange unless you're absolutely sure the pointer is never 
taken off the stack (the call stack is shared between the C and D 
code). Once you're sure the memory is no longer referenced on the 
C heap, you can remove the root or range with GC.removeRoot and 
GC.removeRange.
