A run-time testcase:

[hjl@gnu-34 483.xalancbmk]$ cat x.cc
extern "C" void abort (void);

class Foo 
{
public:
  Foo (void) : xxx (1) {};
  const int xxx;
};
Foo *
bar ()
{
  return new Foo;
}

int
main ()
{
  Foo *p = bar ();

  if (p->xxx != 1)
    abort ();
  return 0;
}
[hjl@gnu-34 483.xalancbmk]$ /export/gnu/import/rrs/158918/usr/bin/g++  -O2 x.cc
[hjl@gnu-34 483.xalancbmk]$ ./a.out
