Confirmed. This used to work in 4.1 where we got the following error
(which does not earn the prize for the prettiest error message ever):

g/x> /home/bangerth/bin/gcc-4.1.1/bin/c++ -c x.cc
x.cc: In function 'int main()':
x.cc:7: error: size of array has non-integral type 'T'
x.cc:1: error: size of array has non-integral type 'T'
x.cc:1: error: size of array has non-integral type 'T'
x.cc:7: error: invalid initialization of reference of type 'unsigned int
(&)[1]' from expression of type 'unsigned int [2]'
x.cc:1: error: in passing argument 1 of 'void f(T (&)[N]) [with T = unsigned
int, T N = ((T)2)]'
x.cc: In function 'void f(T (&)[N]) [with T = unsigned int, T N = ((T)2)]':
