The following code (original code courtesy of Mike Zingale, reduced by yours
truly) gives an ICE with current mainline:
module box_module
type box
integer :: m = 0
end type box
end module box_module
module sort_box_module
contains
subroutine heapsort_box(cmp)
interface
subroutine cmp(a)
use box_module
type(box) :: a
end subroutine cmp
end interface
optional :: cmp
end subroutine heapsort_box
end module sort_box_module
module boxarray_module
use box_module
implicit none
type boxarray
type(box), allocatable :: bxs(:)
end type boxarray
contains
subroutine boxarray_build_l(ba)
type(boxarray) :: ba
allocate(ba%bxs(1))
end subroutine boxarray_build_l
subroutine boxarray_sort()
use sort_box_module
call heapsort_box
end subroutine boxarray_sort
end module boxarray_module
The ICE is:
boxarray.f90: In function boxarray_build_l:
boxarray.f90:34: internal compiler error: in fold_convert, at fold-const.c:2330
And its backtrace is:
Breakpoint 1, fold_convert (type=0xb7c2dbd0, arg=0xb7c2f33c)
at ../../../trunk/gcc/fold-const.c:2330
2330 gcc_unreachable ();

I couldn't reduce it further, I think the ICE needs the optional argument to
heapsort_box and the default initialization in type box.

------- Comment #1 from fxcoudert at gcc dot gnu dot org 2007-04-18 22:40 -------
It's a 4.3 regression, because it compiles with 4.2 (although I haven't looked
at the generated code).

(In reply to comment #1)
Move use sort_box_module up to module level and it compiles fine. This is yet
another derived type association regression that I would swear is identical to
one of the testcases:)
It's mine.
