I am able to compile this using -std=c++0x (not even -std=gnu++0x):
#include <iostream>
int main()
{
int test[] = {1,2,3};
std::cout << test[0] << test[1] << test[2];
test = {4,5,6};
std::cout << test[0] << test[1] << test[2] << std::endl;
}
it compiles without warnings (-Wall -Wextra -pedantic) and prints 123456.
Tested on GCC 4.4.3 and GCC 4.5.1-pre9999
The C++0x final draft (N3092) says, under 5.17/9 [expr.ass]
A braced-init-list may appear on the right-hand side of
an assignment to a scalar [...]
an assignment defined by a user-defined assignment operator [..]
The standard does not allow assignment from a braced-init-list to arrays (and
if was allowed, then, logically, assignment of arrays to arrays would be
allowed as well)

Summary: incorrectly allows assignment to arrays from braced-
init-list (c++0x)
