--- Comment #1 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
Confirmed.  We get:

85977.C: In function ‘void bar()’:
85977.C:4:13: error: no matching function for call to ‘foo(<brace-enclosed
initializer list>)’
  foo({1,2,3});
             ^
85977.C:2:6: note: candidate: ‘template<int N> void foo(const long int (&)[N])’
 void foo(const long (&arr)[N]) {}
      ^~~
85977.C:2:6: note:   template argument deduction/substitution failed:
85977.C:4:13: note:   mismatched types ‘long int’ and ‘int’
  foo({1,2,3});
             ^
