Subject: debugger issue

I'm running into an unexpected issue with the debugger, and I'm hoping someone
here can help me out.  I' ve got a short program like this (stolen directly
from zenspider's RubyInline tutorial):

-=-=-=-=-=-=-=-=-=-=-=-=-=-==-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
#!/usr/local/bin/ruby -w

class Array

  def average
    result = 0
    self.each { |x| result += x }
    result / self.size.to_f
  end

end

max_loop = (ARGV.shift || 5).to_i
max_size = (ARGV.shift || 100_000).to_i
a = (1..max_size).to_a

1.upto(max_loop) do
  avg = a.average
  $stderr.print "."
end
$stderr.puts ""
-=-=-=-=-=-=-=-=-=-=-=-=-=-==-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-


Everytime I step to line 7 (the self.each ... line) or do a step nnn which
executes line 7, the debugger stops there.  Neither step or next will move
past this line.  If I try to continue the program, it will run to the next
breakpoint or end of the program.

Any idea what's going on?  Is this a bug in the debugger, or am I
misunderstanding something?
