I also see it on x86_64-unknown-linux-gnu and x86_64-apple-darwin10.6.0. As
shown by the following test, there is a bus error for the exponents is the
range 127 to 142 (I did not check exponents above 200;-):
program z
implicit none
integer ::i
real(kind=16) :: q
do i=1,126
q=2.0_16**i
write(*,*)i,q
end do
do i=200,143,-1
q=2.0_16**i
write(*,*)i,q
end do
! write(*,*)'127'
! q=2.0_16**127
! write(*,*)i,q
write(*,*)'142'
q=2.0_16**142
write(*,*)i,q
end program z
