So the last paragraph above is incorrect, and "the previous commit" is
not broken?  Then what about the information in

  https://debbugs.gnu.org/cgi/bugreport.cgi?bug=43152#65
  https://debbugs.gnu.org/cgi/bugreport.cgi?bug=43152#68
  https://debbugs.gnu.org/cgi/bugreport.cgi?bug=43152#71

And the rest of the discussion about verify.h being the culprit?
