            Bug ID: 67885
           Summary: ICE on using parameter array in block
           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: ---

Using a parameter array in a block with an inner block :

$ cat z1.f90
program p
   block
      real, parameter :: a(2) = 1.0
      real :: x(2)
      x = a
      block
      end block
   end block
end


$ gfortran -g -O0 -Wall -fcheck=all -fno-frontend-optimize z1.f90
internal compiler error: in gfc_process_block_locals, at
fortran/trans-decl.c:6096

Same issue when using other intrinsic types, etc.

---

Compiles without parameter attribute :

$ cat z2.f90
program p
   block
      real :: a(2) = 1.0
      real :: x(2)
      x = a
      block
      end block
   end block
end
