As it should, current is never reassigned.
You only need one var, next. Of course I didn't read the entire 
thread chain so, I'm probably missing something.

import std.experimental.allocator;

void main() {
        struct S { S* next; }
        S* _foo;
        foreach (e; 0 .. 10)
                _foo = theAllocator.make!S(_foo);
        S* next;

        next = _foo;
        while(next !is null) {
                auto nextT = next.next;
                theAllocator.dispose(next);
                next = nextT;
        }
}

Thanks for your response. So next is never null, and thus there 
is an infinite loop, correct? If so, why does dub indicate that 
all tests are complete?
