Jonathan Wakely e182158261 PR libstdc++/86751 default assignment operators for std::pair ... The solution for PR 77537 causes ambiguities due to the extra copy assignment operator taking a __nonesuch_no_braces parameter. By making the base class non-assignable we don't need the extra deleted overload in std::pair. The copy assignment operator will be implicitly deleted (and the move assignment operator not declared) as needed. Without the additional user-provided operator in std::pair the ambiguity is avoided. PR libstdc++/86751 * include/bits/stl_pair.h (__pair_base): New class with deleted copy assignment operator. (pair): Derive from __pair_base. (pair::operator=): Remove deleted overload. * python/libstdcxx/v6/printers.py (StdPairPrinter): New pretty printer so that new base class isn't shown in GDB. * testsuite/20_util/pair/86751.cc: New test. * testsuite/20_util/pair/ref_assign.cc: New test.
