(I remember tricky details | only about copy constructor and assignment, actually) Careless addition of constructors or destructors can indeed change an ABI. However in the specific case at hand, the addition is that of a non-copy default constructor whose only potential impact is that of changing a POD to non-POD. However, both _List_iterator and _List_const_iterator are already non-POD as they have a constructor to convert from a _List_node_base*. So the patch is ABI-neutral. -- Gaby -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19510
