[Bug c++/14469] New: Cannot compile TAO (regression)

[schmid at snake dot iap dot physik dot tu-darmstadt dot de]

I cannot compile the file ACE_wrappers/Param_Tests/any.cpp from the ACE-5.4
+TAO-1.4+CIAO-0.4 distribution when the optimization at the -O2 level or higher 
is enabled. This is a regression with respect to gcc 3.3.

This reduces to

=============================
struct A
{
  A();
};

struct B
{
  B(const A*);
};

struct C
{
  void foo(int);

  B b;
};

void C::foo(int)
{
  b = new A;
}
=============================

which is a duplicate of PR 14477.
