/PENDING_INSTANTIATIONS
       /PENDING_INSTANTIATIONS[=n]
       /PENDING_INSTANTIATIONS=64(D)

    Limit the depth of recursive instantiations so that infinite
    instantiation loops can be detected before some resource is
    exhausted. The /PENDING_INSTANTIATIONS qualifier requires a
    positive non-zero value as argument and issues an error when
    n instantiations are pending for the same class template. The
    default value for n is 64.
