    libstdc++: Qualify calls to std::_Destroy and _Destroy_aux
    
    These calls should be qualified to prevent ADL, which can cause errors
    for incomplete types that are associated classes.
    
    libstdc++-v3/ChangeLog:
    
            * include/bits/alloc_traits.h (_Destroy): Qualify call.
            * include/bits/stl_construct.h (_Destroy, _Destroy_n): Likewise.
            * testsuite/23_containers/vector/cons/destroy-adl.cc: New test.
