Is
There are two problems involved in this PR.
First, as Clang's ubsan detects, we are using static_cast to convert
from _Rb_tree_node_base* to _Rb_tree_node_Val* in cases where there
is no _Rb_tree_node_Val at that address (_M_impl._M_header is just
an _Rb_tree_node_base). That's undefined

(I mean, won't some target align the structure more than its only field)?
Hmm, maybe.
