The 8.84 compiler fails to compile the following cut-down code with /64. There is no problem with 32-bit compilation, and the problem goes away if the second argument to DCMPLX is "0.0".
| Code: | subroutine FUNMR(A,n,C)
implicit none
integer::n,i,j
complex*16, dimension(0:n-1, 0:n-1) :: C
complex*16 dcmplx
real :: A(0:N-1,0:N-1)
do i=0,n-1
do j=0,n-1
C(i,j)=dcmplx(A(i,j),0)
end do
end do
end subroutine |
The compiler output:
| Code: | T:\solanki>ftn95 /64 mrs1.f90
