g++-4.7.0 emits an error for the following piece of code.

------------------------- BEGIN -----------------------------
#include <cstddef>
#include <new>

template <typename T = size_t>
void f ()
{
   size_t coord [2][2];
   new (&coord) size_t [2][2] 
   {
      {0,0},
      {0,0},
   };
}

int main ()
{
   f<>();
}
-------------------------  END  -----------------------------
The error message was 
error: parenthesized initializer in array new [-fpermissive]
sorry, unimplemented: cannot initialize multi-dimensional array with initializer

I observed the same behavior on 4.8.0. The problem only occurs inside function template according to my test. If I made f an ordinary function, the code was accepted. Clang 3.2 and Visual Studio 2012 all accept the code. These facts led me to assume this is a bug in g++.

Below is my g++ version.
