Bug ID: 102729
Summary: Assumed rank: ICE when passing noncontiguous to
CONTIGUOUS assume rank (assumed-rank loop handling)
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: burnus at gcc dot gnu.org
Target Milestone: ---
Related: PR 102708, PR54753, PR102641
That's an extended version of gfortran.dg/c-interop/fc-descriptor-7.f90
- - - -
integer(C_INT), target :: bb(10,10)
call ftest (bb(2:10:2, :), is_cont=.false._c_bool)
...
subroutine ftest_ar (a, is_cont)
use iso_c_binding
integer(C_INT) :: a(..)
logical(c_bool), value, intent(in) :: is_cont
...
!call ftest_ar_con (a, is_cont=.true._c_bool) ! <<< fixme!
end subroutine
subroutine ftest_ar_con (a, is_cont)
use iso_c_binding
integer(C_INT), contiguous :: a(..)
logical(c_bool), value, intent(in) :: is_cont
....
That gives an ICE as the loop handling does not work
for rank == -1 (= assumed-rank arrays)
124 | call ftest_ar_con (a, is_cont=.true._c_bool) ! <<< fixme!

This is the same ICE previously reported as PR100194.
