[Bug fortran/38504] double minus sign when printing integer?

[dfranke at gcc dot gnu dot org]

Sort of confirmed. You are aware that 'value-1' corresponds to
'-HUGE(value)-1', which is out of range for integer numbers of that kind?

Reduced testcase:

IntAdtest
  integer, parameter :: i8_ = Selected_Int_Kind(18)  ! = integer*8
  integer(i8_) :: value

  value = -9223372036854775807_i8_
  write(*, FMT="(i22)") value, -HUGE(value)

  value = -9223372036854775807_i8_ -1
  write(*, FMT="(i22)") value, -HUGE(value)-1
end program IntAdtest
