The problem is that a COMPOUND_LITERAL_EXPR doesn't have CONSTRUCTOR as its
DECL_INITIAL.  Either this is a FE bug (tree.def says that it should be
CONSTRUCTOR), or we should just tweak optimize_compound_literals_in_ctor not to
recurse if TREE_CODE (init) is not CONSTRUCTOR.

Correct source would be
struct bla{char **a;};void test(void){struct bla b = {.a =(char*[]){"a","b"}};}
