[Bug c++/33885] New: member reference to a temporary object being deleted too eary

["gzljg at hotmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

class A{
// ....
};

class B{
public:
  explicit B(const A& a)
    : i_a(a)
  {
  }
  ~B()
  {
  }
private:
  const A& i_a;
};

A returnA( const char* arg )
{
   return A(/*arg*/);
}

foo()
{
   const A& aRef = returnA("FirstObject");  // ..... (1)
   {
     const B b(returnA("SecondObject"));    // ..... (2)
     ///...
     typedef int outofscope_block;          // ..... (3)  
   }
   typedef char outofscope_function;        // ..... (4)
}

temporary object created and referenced by aRef is being deleted when aRef goes
out of scope in foo, as Expected.
temporary object created and referenced by B::i_a is being deleted right after
object b's construction, Not expected.  It should(?) have the same life time as
the B::i_a(thus b), such as deleted _after_ line (3) --- If this assumpsion is
false, then what's the difference between a 'plain reference' and 'member
reference' herein??

BTW, it works as expected on SunCC compiler. It core dumps on gcc 3.3.3 while
having (empty/invalid) data for i_a on gcc 4.1.2 but not coring.
