Confirmed.  Even with -fvisibility=hidden we have

    28: 0000000000000000    17 FUNC    WEAK   HIDDEN    13 _ZN10TestObjectC2Ev
    29: 0000000000000000    17 FUNC    WEAK   HIDDEN    13 _ZN10TestObjectC1Ev
    33: 0000000000000000    46 FUNC    WEAK   DEFAULT   15
_ZNSt4pairI10TestObje
ctPv
    37: 0000000000000000    46 FUNC    WEAK   DEFAULT   15
_ZNSt4pairI10TestObje
ctPv

You can work around this by linking the shared library with -Bsymbolic to
force local symbol resolution.
