This probably isn't arch-dependent. More likely you just have a
different version of libstdc++. Can you share how the std::unique_ptr
layout looks like for you. This is how my std::unique_ptr looks like
(from libstdc++.so.6.0.22):
(lldb) fr var X -R -T
(std::unique_ptr<int, std::default_delete<int> >) X = {
(std::unique_ptr<int, std::default_delete<int> >::__tuple_type) _M_t = {
(std::_Tuple_impl<0, int *, std::default_delete<int> >)
std::_Tuple_impl<0, int *, std::default_delete<int> > = {
(std::_Head_base<0, int *, false>) std::_Head_base<0, int *, false> = {
(int *) _M_head_impl = 0x0000555555768c20
}
}
}
}
