Reduced single file test-case:
$ cat define_type.f90
subroutine ni (ps)
type vector
real x, y
end type
type quad_inductor
type (vector) v1, v2
end type
type (quad_inductor), dimension(inout) :: ps
integer :: dl, nk = 1.0
fo = 1.0
if (f == 1) then
nk = 0.0
fo = 0.0
end if
ot = nk * 0.5
gb = -fo * 0.5
wu = fo * 0.5
up = nk * 0.1
xe = up * 0.1
do lx = 0, 7
ps%v2%y = -wu
ps(dl)%v1%x = xe + 1.0
ps(dl)%v1%y = wu - tn
end do
do lx = 0, 7
ps(dl)%v1%x = 0.1 - ot
ps(dl)%v1%y = 0.1 - wu
end do
end
Can be reproduced on x86_64-linux-gnu.
