--- Comment #2 from Martin Sebor <msebor at gcc dot gnu.org> ---
Actually, it's slightly more complicated. string_constant does fold the
reference to the STRING_CST "2" but with the size of 1 because it doesn't
consider the implicit zero that follows the '2'. Simply changing
string_constant to look at the next element to see if it's zero isn't enough to
handle the case when the zero is implicit because fold_ctor_reference called to
extract the element value only handles explicit initializers.
