in data.c to see the computed offset values. The first chunk comments out
a check for a constant ar->start[] value, so that I get back to where
get_data_index is called. For this code
implicit none
type :: a
real :: x(3)
end type a
integer, parameter :: n = 3
type(a) :: b(n)
real, parameter :: d1(3) = (/1., 2., 3./)
real, parameter :: d2(3) = (/4., 5., 6./)
real, parameter :: d3(3) = (/7., 8., 9./)
integer :: i, z(n)
data (b(i), i = 1, n) /a(d1), a(d2), a(d3)/
data (z(i), i = 1, n) / 1, 2, 3/
print *, z(1), b(1)
print *, z(2), b(2)
print *, z(3), b(3)
end
I get
REMOVE:kargl[248] gfc4x -o z pr41807.f90
offset: 0

offset: 2
offset: 0
offset: -1
offset: -1

3 0.0000000 0.0000000 0.0000000
The first 3 offset values is from the data statement for the
z(3) array. The next 3 are for the array b(3) of the derived
type a. My conclusion to this point is that the array spec for
an array of a derived type is not properly set, or we're looking
at the wrong array spec.
