Master Listing

Submitted by Nat McIntosh (mcintosh@cs.rice.edu)

The current revision of the parser/unparser crashes when you feed it a
simple program containing a statement function definition and use. The
following is an example:

      program mumble
      integer q, r
      doublit(x) = x + x
      read *, q
      r = doublit(q)
      print *, r
      end

I'm not sure when this bug was introduced, so I can't tell you which
versions of the D system it applies to. This looks like a good program
to add to our regression test suite, I would say. I looked at it a bit
in the debugger, and it appears that the routine that's crashing is
"ftt_Listing" (the AST is being built correctly, in other words, but
then the FortTextTree build fails).
