--- Comment #1 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
Confirmed. The test pr17143.f90 relies on wrapping on overflow, so it's
probably
a WONTFIX. Reduced test for power_8.f90:

  integer(1) :: j
  j = 7
  print *, (-2_1) ** j
  print *, (-512_8) ** j
end

There are no runtime errors if I replace j with 7.
