Marc, this is the relative diff to go back to what I had earlier, with
the size in the _List_impl in case you want to aply it locally (the
dg-error tests are off-by-one with this patch)
Thanks. For PR 61347, to avoid offsetof, I will actually need to
change:
- __detail::_List_node_base _M_node;
- size_t _M_size;
+ _List_node<size_t> _M_node;
and store the size in _M_node._M_data. Since I will have to touch it
anyway, don't feel forced to move it to _M_impl.
