   1 ## Check that the sanity check for an inconsistent header works.
   2 ## The first word contains the bad value for CodeWords, 0xf, which indicates
   3 ## that we need 0x11110 << 2 =  120 bytes of space for the unwind codes.
   4 ## It follows that the .xdata section is badly formed as only 8 bytes are
   5 ## allocated for the unwind codes.
