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 

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 ) ).*( ::x ) = 2;

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

The following code snippet makes the compiler ICE. Affects at least 4.8.2 and
4.9.3. Does not seem to affect 5.x. Compile with --std=c++11

==

#include 

template< class T >
struct Tmpl
{
  ~Tmpl() noexcept( std::is_nothrow_destructible< T >::value )
  {}
};

struct Empty
{
};

struct Foo
{
  ~Foo()
  {}

  Tmpl< Empty > member;
};

int main()
{
}

The following does not compile:

== test.cc =

{
  template unsigned v 
  struct Foo
  {
unsigned value = v;
  };
};


$ g++-4.8 -c -std=c++11 test.cc

Status: UNCONFIRMED

The following code causes an ICE:

 test.cc =
struct B {};
struct A
{
  A( B );
};

struct Bar
{
  template unsigned v 
  struct Foo
  {
A z = B();
unsigned value;
Foo(): value( v ) {}
  };

  struct Baz
  {
Foo 8  foo1;
Foo 1  foo3;
  };
};

Bar::Baz baz;

test.cc:14:21: internal compiler error: in gimple_add_tmp_var, at

P.S. This might possibly be related to bug 58187.
