   1 ## Check that error handling for going past the unwind data works.
   2 ## .xdata below contains bad opcodes in the last word.  The last byte, 0xe0,
   3 ## indicates that we have come across alloc_l, which requires 4 bytes. In this
   4 ## case, unwind code processing will go past the allocated unwind data.
