- I was dismayed to find that stack_return_from_v86 was terribly incomplete. 

It did an exception, and then the real code seemed to be commented out
  with an #if 0...#endif.  I put a panic there, asking people to please
  report how they arrived at that condition, and enabled the #if 0 code.
  This was pointed out by luca abeni <l_abeni@hotmail.com>.
