 46 bytes in 1 blocks are definitely lost
    at  notify_alloc (heap.c:254)
    by  RtlAllocateHeap (heap.c:1700)
    by  RtlFormatCurrentUserKeyPath (reg.c:846)
    by  test_symlinks (registry.c:1527)
    by  func_registry (registry.c:1655)

(Perhaps we should win_skip if RtlFormatCurrentUserKeyPath fails in
test_symlinks, but that doesn't seem likely?)
