This program aborts when compiled with llvm-gcc. This is failing on the
buildbots during a build of gfortran:

$ cat testcase.i

struct __mpz_struct {
  int _mp_size;
};
typedef struct __mpz_struct mpz_t[1];
typedef struct gfc_expr {
  mpz_t *shape;
  union {
    struct __mpz_struct integer[1];
  } value;
} gfc_exec_op;
struct gfc_array_ref {
  struct gfc_expr *start[7];
};
void gfc_copy_array_ref (struct gfc_array_ref *src) {}

$ llvm-gcc -c testcase.i
Assertion failed: (Ty->isSized() && "Cannot getTypeInfo() on a type that is
unsized!"), function getTypeSizeInBits, file
/Users/void/llvm/llvm.src/lib/Target/TargetData.cpp, line 393.
testcase.i: In function ‘gfc_copy_array_ref’:
testcase.i:14: internal compiler error: Abort trap
