Probably issue 9614 - Uninitialized holes in function stack 
frames confuses GC - https://issues.dlang.org/show_bug.cgi?id=9614

    static void stomp() {ubyte[1024] x;}
    stomp();
    GC.collect();
    writeln(cast(size_t) cast(void*) new Object == 
*pointerInDisguise);
        /* prints "true" => memory is reused */

    GC.collect();
    writeln(cast(size_t) cast(void*) new Object ==

        /* prints "true" => memory is reused */
}
