Here is the reduced testcase (fails on darwin as well):

typedef struct gfc_array_ref {
  struct gfc_expr *start[7];
} gfc_array_ref;

typedef struct {
  int _mp_alloc;
} __mpz_struct;

typedef __mpz_struct mpz_t[1];

typedef struct {
} __mpfr_struct;

typedef struct gfc_expr {
  mpz_t *shape;
  union {
    mpz_t integer;
  } value;
} gfc_expr;

gfc_array_ref * gfc_copy_array_ref (gfc_array_ref * src) { }

It asserts asking alignment of [1 x %struct.__mpz_struct] which is the
LLVM type corresponding to union inside gfc_expr.
