--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
The error started with r13-2968:

c++: fix triviality of class with unsatisfied op=

cxx20_pair is trivially copyable because it has a trivial copy constructor
and only a deleted copy assignment operator; the non-triviality of the
unsatisfied copy assignment overload is not considered.
