hades [TEST] cat bug-mvbits.f90 
program main
  implicit none

  integer :: a( 1 ), b( 1 )
  integer :: x, y

  a = 1
  b = 0
  x = 1
  y = 0

  call mvbits (a, 0, 1, b, 1)
  call mvbits (x, 0, 1, y, 1)

  write (*, *) 'a: ', a
  write (*, *) 'x: ', x
  write (*, *)
  write (*, *) 'b: ', b
  write (*, *) 'y: ', y
  write (*, *)

  if ( all (b == y) ) then
     write (*, *) 'GOOD:  b == y'
  else
     write (*, *) 'BAD:  b /= y'
  end if

end program main

hades [TEST] ./a.out 
 a:            1
 x:            1

 b:            0
 y:            2

 BAD:  b /= y
