--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> ---
For completeness, the error for std::list now shows:
a.cc: In instantiation of ‘void my_allocator<T>::construct(U*, Args&& ...)
[with U = int; Args = {int}; T = std::_Rb_tree_node<int>]’:
which is consistent with maps and sets now.
I actually consider it a bug that you don't get the assertion for other
containers too! The unordered containers and forward_list should not bother
constructing a rebound allocator to call construct/destroy.
