It appears to be an in-lining issue. This reduced case
program main
implicit none
call build (77)
contains
subroutine build (order)
integer :: order, i, j
call test (1, order, 3, (/ (i, i = 1, order, 3) /))
call test (order, 1, -3, (/ (i, i = order, 1, -3) /))
do j = 0, 1
call test (order + j, order, 5, (/ (i, i = order + j, order, 5) /))
end do
end subroutine build
subroutine test (from, to, step, values)
integer, dimension (:) :: values
integer :: from, to, step, last, i
last = 0
do i = from, to, step
last = last + 1
if (values (last) .ne. i) call abort
end do
if (size (values, dim = 1) .ne. last) call abort
end subroutine test
end program main
gives
laptop:kargl[230] gfc4x -c -g -O3 array_constructor_11.f90
array_constructor_11.f90:6:0: internal compiler error: in output_die, at
dwarf2out.c:10649
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
laptop:kargl[231] gfc4x -c -g -O3 -fno-inline array_constructor_11.f90
where the last command succeeds.
Note, if I remove any one of the calls to test() or remove either
if-statement within test(), the ICE goes away.
