[f2py] Re: Bug with string concatenation

Apologies, I cut out too much of the code. Here is the code that  
produces the problem:

       SUBROUTINE TEST ()
       CHARACTER WORD*20
       PARAMETER (WORD = 'HELLO' // 'WORLD' )
       END

If I try and compile it with f2py, I get the traceback I sent  
previously. If I compile e.g. with gfortran -c there is no problem.

Is this a bug?

Thanks,

Thomas
