Description of problem:
The following program compiles fine with g77, but leads to an internal error with gfortran:

      SUBROUTINE t2
      CHARACTER  CA*1
      CHARACTER*1  CQ(1)
      EQUIVALENCE (CQ(1),CA(1:1))
      END

[dumas@chapelle dzebra]$ gfortran -c -o res.o t2.f
 In file t2.f:5

      END                                                               
                                                                       1
 Internal Error at (1):
 find_array_spec(): Missing spec


In a similar code, but with an undeclared array, there is the same error message. This time the code is broken, but te error message is wrong:
      SUBROUTINE t     
      EQUIVALENCE (I, J(1))
      END
When compiled leads to

[dumas@chapelle dzebra]$  gfortran -c -o t.o  t.f 
 In file t.f:3

      END                                                               
                                                                       1
