Bug ID: 77371
Summary: ICE in force_constant_size, at gimplify.c:671 (... and
others)
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: [email protected]
Target Milestone: ---
Some snippets with allocatable scalars (valid code) combined with
OpenACC. Similar issue for "pointer" instead of "allocatable".
$ cat z1.f90
program p
character(:), allocatable :: z
!$acc parallel
z = 'abc'
!$acc end parallel
print *, z
end
$ gfortran-7-20160821 -fopenacc z1.f90
z1.f90:3:0:
!$acc parallel
