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.

README
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
