Subject: Problem with 1.8 / optparse.rb from within debugger

Hi,

Am I the only who get the following error when trying to go step-by-step in
the debugger in the optparse code?

469 [13:11] roberto@caerdonn:ruby/LDAP> ruby -r debug ldap-infocentre.rb -d
Debug.rb
Emacs support available.

ldap-infocentre.rb:26:RCS_REV = "1"
(rdb:1) b 243
Set breakpoint 1 at ldap-infocentre.rb:243
(rdb:1) c
/usr/local/lib/ruby/1.8/optparse.rb:1621: unexpected return

472 [13:21] roberto@caerdonn:ruby/LDAP> ruby -v               
ruby 1.8.0 (2003-09-09) [i386-freebsd5]

Line 1621 in optparse.rb is:

-=-=-
    def options
      @optparse ||= OptionParser.new
      block_given? or return @optparse
      begin
    yield @optparse                             <<<<<<<< line 1621
      rescue ParseError
    @optparse.warn $!
    nil
      end
    end
-=-=-

and the code it is trying to execute is the following. Works fine when run
outside "-r debug".

-=-=-
  argv.options do |opts|
    opts.banner = banner
    opts.on("-d", "--debug", "Debugging") {
      |$debug|
      $debug = true
    }                   
    opts.on("-h", "--help", "Help") {
      print opts
      exit 0
    }                   
    opts.on("-u", "--uid-check", "Check uid & acronym") {
      |uid_check|
    }
    opts.parse!
  end
-=-=-
