            Bug ID: 114525
           Summary: Incorrect code generated when setting a value through
                    a pointer-to-member on a ternary returning an object
                    reference
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dragonroot at gmail dot com
  Target Milestone: ---

The following program incorrectly outputs 1 on every GCC I've tried (via
godbolt.org), while every clang version there correctly outputs 2.

==============
#include <stdio.h>

struct Foo
{
  int x;
};

Foo & get( Foo & v )
{
  return v;
}

int main()
{
  Foo v;

  v.x = 1;

  bool cond = true;

  ( cond ? get( v ) : get( v ) ).*( &Foo::x ) = 2;

  // Should output 2, but outputs 1
  printf( "%d\n", v.x );
}
==============
