Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org

Target Milestone: ---
Changed between 20200823 and 20201004 :
(z1 is invalid, z2 looks valid)
$ cat z1.f90
program p
character(:), parameter :: a(0) = reshape(['a'], [0])
end
$ cat z2.f90
program p
character(*), parameter :: a(0) = reshape(['a'], [0])
end
$ gfortran-11-20200823 -c z1.f90
z1.f90:2:34:
2 | character(:), parameter :: a(0) = reshape(['a'], [0])
| 1
Error: Entity 'a' at (1) has a deferred type parameter and requires either the
POINTER or ALLOCATABLE attribute
