Reduced. Hope I haven't turned it into something invalid.
typedef unsigned int size_t;
namespace base
{
template < size_t Size, size_t ByteAlignment > struct AlignedMemory;
template < typename Type > struct StaticMemorySingletonTraits
{
};
template < typename Type > base::AlignedMemory < sizeof (Type), 0 >
StaticMemorySingletonTraits < Type >::dead_;

Even more simplified and turned (hopefully) into valid testcase:
typedef __SIZE_TYPE__ size_t;
template <size_t T, size_t U>
struct A;
template <typename T> struct B
{
static A <sizeof (T), 0> x;
};
template <typename T>
A <sizeof (T), 0> B <T>::x;
As expected, started with
http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=192141
I knew why I was initially proposing the far less risky hack.
