std::unique_ptr allows construction from std::unique_ptr of derived
type as per [unique.ptr.single.asgn] and [unique.ptr.single.ctor]. If
std::default_delete is used with std::unique_ptr, then after such
construction a delete is called on a pointer to base. According to
[expr.delete] calling a dele

When std::seed_seq is constructed from random access iterators we can
detect the internal vector size in O(1). Reserving memory for elements
in such cases may avoid multiple memory allocations.

Looks like the answer is "yes". There are tests for that in

This patch provides compile time diagnostics for common misuse of
[locale.convenience] functions with std::string as a character type.

Final bits for libstdc/71579
std::common_type assertions attempt to give a proper 'required from
here' hint for user code, do not bring many changes to the
implementation and check all the template parameters for completeness.
In some cases the type could be checked for completeness more than
once
Looks like the last patch was not applied. Do I have to change something in
it?
