If you look at the definition of "struct variable7", you'll see that
it starts:

  struct variable7 {
    u_char          magic;      /* passed to function as a hint */
    :
  }

The magic number is therefore restricted to the range 0..255

Because this is value outside the valid range for a u_char field.

Change the #define to use a different number, less than 256.
