   2 /* This is a test program from Lee Kindness which used to fail on V
   3    because gcc implements the nested function mumbo jumbo using self
   4    modifying code on the stack, at least on x86 and amd64.  It now
   5    works transparently because by default V now generates
   6    self-checking translations for translations taken from stack-like
   7    segments.
