You can simplify the test case. Compiling the following code still segfaults:

typedef struct {
  unsigned long long house;
} struct_0;


typedef union {
  unsigned cows;
  unsigned char c;
} union_1;


typedef struct {
  struct_0 s0;
  union_1 s1;
} struct_2;

struct_2 s = {
  .s0 = {
    .dog = 0x00000009,
  },

  .s1 = {
    .cows = 0x00000055,
    .c = 1,
  },
};

Also, would it be better to add this test to an existing file (e.g., test/Sema/designated-initializers.c) rather than creating a new file?
