            Bug ID: 68154
           Summary: ICE on initializing character parameter array
                    (explicit, implied)
           Product: gcc
           Version: 5.2.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: gerhard.steinmetz.fortran@t-online.de
  Target Milestone: ---

Some variants of initializing a character parameter array
(explicit-shape, implied-shape) are not working :


$ cat z1.f90
program p
   character(1), parameter :: x1(2) = 'a'
   character(*), parameter :: x2(2) = x1
   character(*), parameter :: x3(*) = x1
end

$ gfortran -g -O0 -Wall -fcheck=all z1.f90
f951: internal compiler error: Segmentation fault


$ cat z2.f90
program p
   character(*), parameter :: x1(2) = 'a'
   character(*), parameter :: x2(2) = x1
   character(*), parameter :: x3(*) = x1
end

$ gfortran -g -O0 -Wall -fcheck=all z2.f90
f951: internal compiler error: Segmentation fault
