Bug ID: 99206
Summary: [11 Regression] ICE in add_init_expr_to_sym, at
fortran/decl.c:1980
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: gscfq@t-online.de
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

Confirmed.
gcc-10 emits an appropriate error message for z1 and accepts z2.

--- Comment #2 from anlauf at gcc dot gnu.org ---
As a sidenote:
print *, len (reshape (['a'], [0]))
end
This prints 0 for gcc-11, and the correct value 1 for 10.2.1.
Do we screw up things during simplification?

Make sure that the string length is properly set during simplification
even when the resulting array is zero-sized.
