And here is a testcase which fails in 3.4.5 and above:
int* block;
void final(unsigned int j){
  int * lsm_tmp1;
  unsigned char * data;
  unsigned int i;
  data = (unsigned char *) "";
  lsm_tmp1 = block;
  i = 0;
  do {
    if (j == 4294967233)
    {
      lsm_tmp1 = (int *) (data + 4294967233);
      j = 1;
    }
    i = i + 1;
  } while (i != 8);
  block = lsm_tmp1;
}
