[Thomas dot Koenig at online dot de]

The same bug is triggered if the assigned variable
is equivalenced:

$ cat assign4.f
      program main
      integer i
      integer j
      equivalence (i,j)
      assign 1000 to i
      goto j
 1000 continue
      end
$ gfortran assign4.f
 In file assign4.f:5

      assign 1000 to i
                                                                       1
Warning: Obsolete: ASSIGN statement at (1)
 In file assign4.f:6

      goto j
           1
Warning: Obsolete: Assigned GOTO statement at (1)
assign4.f: In function 'MAIN__':
assign4.f:5: internal compiler error: tree check: expected class
