I describe the problem from 'emacs -Q':
scheme-mode.el isn't able to correctly parse the file:
racket-5.0.2/collects/drracket/tool-lib.rkt
When I open the file, go to position (79,0)
and execute `forward-sexp' I get
Scan error: "Unbalanced parentheses", 2852, 65105

The expected behaviour is for the point to be moved at the end
of the file behind the last closing parenthesis to position (1663,85).
When I move the point at the end of the file behind the last closing
parenthesis and do `backward-sexp' the point is moved to line
the point is moved to position (152,19) instead to (79,0), where
the next character is an opening curly brace.

This error occurs neither under fundamental-mode nor under lisp-mode.
I attach the problematic file to this report.

Thank you very much,
Alexander Haeckel

  @{Use this function to expand the contents of the definitions
    window for use with external program processing tools.
    
    This function uses
    @racket[drracket:eval:build-user-eventspace/custodian]
    to build the user's environment.
    The arguments @racket[language-settings], @racket[init], and
    @racket[kill-termination] are passed to
    @racket[drracket:eval:build-user-eventspace/custodian].
    
    The @racket[input] argument specifies the source of the program.
    
    The @racket[eval-compile-time-part?] argument indicates if
    @racket[expand]
    is called or if
    @racket[expand-top-level-with-compile-time-evals]
    is called when the program is expanded.
    Roughly speaking, if your tool will evaluate each expression
    itself by calling
    @racket[eval]
    then pass @racket[#f]. Otherwise, if your tool
    just processes the expanded program, be sure to pass
    @racket[#t].
    
    This function calls
    @method[drracket:language:language<%> front-end/complete-program]
    to expand the program. Unlike when the @onscreen{Run} is clicked,
    however, it does not call 
    @method[drracket:language:language<%> front-end/finished-complete-program].
    
    
    The first argument to @racket[iter] is the expanded program
    (represented as syntax) or eof.
    The @racket[iter] argument is called for each expression in the
    expanded program and once more with eof, unless an error is
    raised during expansion.
    It is called from the user's thread.
    If an exception is raised during expansion of the
    user's program, @racket[iter] is not called.
    Consider setting the exception-handler during @racket[init] to
    handle this situation.
    
    The second argument to @racket[iter] is a thunk that
    continues expanding the rest of the contents of the
    definitions window. If the first argument to @racket[iter] was
    eof, this argument is just the primitive
    @racket[void].

    expansion is finished.
    
    It initializes the
    user's eventspace's main thread with several parameters:

    language and its settings. See
    @racket[drracket:language-configuration:language-settings]
    for details on that structure.
    
    If the program is associated with a DrRacket
    frame, get the frame's language settings from the
    @method[drracket:unit:definitions-text<%> get-next-settings]
    method of 
    @racket[drracket:unit:definitions-text<%>].  Also, the most recently chosen language in
    the language dialog is saved via the framework's
    preferences. Apply

    to
    @racket[drracket:language-configuration:get-settings-preferences-symbol]
    for that @racket[language-settings].
    
    The @racket[init] argument is called after the user's parameters
    are all set, but before the program is run. It is called on
    the user's thread. The
    @racket[current-directory] and
    @racket[current-load-relative-directory]
    parameters are not set, so if there are appropriate directories,
    the @racket[init] argument is a good place to set them.
    
    The @racket[kill-termination] argument is called when the main thread of
    the eventspace terminates, no matter if the custodian was
    shutdown, or the thread was killed. This procedure is also
    called when the thread terminates normally. This procedure is
    called from a new, dedicated thread (@italic{i. e.}, not the thread
    created to do the expansion, nor the thread that
    @racket[drracket:eval:build-user-eventspace/custodian] was called from.)})

    The first argument, @racket[name], is the name
    of the mode, used in DrRacket's GUI to allow
    the user to select this mode.
    
    The @racket[surrogate] argument is set to the
    definitions text and the interactions text
    (via the

    method) whenever this mode is enabled.
    
    The @racket[repl-submit] procedure is called
    whenever the user types a return in the interactions
    window. It is passed the interactions editor
    and the position where the last prompt occurs.
    If it 
    returns @racket[#t], the text after the last
    prompt is treated as a program fragment and
    evaluated, according to the language settings.
    If it returns @racket[#f], the text is
    assumed to be an incomplete program fragment, and
    the keystroke is not treated specially.
    
    The @racket[matches-language] predicate is called whenever
    the language changes. If it returns @racket[#t]
    this mode is installed. It is passed the list of strings
    that correspond to the names of the language in the
    language dialog.
    
    Modes are tested in the opposite order that they are
    added. That is, the last mode to be added gets tested
    first when the filename changes or when the language
    changes.
