I found source of problem is ll. 257-280, codes begin with
"if (sizeof(long) == 8) {" .  In PC, we can dike these codes
safely, or to get behind, omit "-g", or add "-O1", in compile
option.

Following is the minimal sample code that cause the problem.

========================================================================
int
foo(void)
{
   if (sizeof(long) == 8) {
      typedef union {
         long i;
         char c[8];
      } comm;
      static volatile comm u;
      u.i = 0x01020304;
      u.i <<= 16, u.i <<= 16;
      u.i |= 0x05060708;
      return u.c[0] == 0x01 && u.c[1] == 0x02;
   }
   return 2;
}
