Subject: Array.new returns nil

Greetings,

Is there anything known about a possible Ruby-1.6.8 bug, where Array.new
starts returning nil ?
I have a class that starts like this:

class Awkstack < Array
  @@sharedtext = nil
  attr_reader :lastrub
  
  def initialize(left)
    @left = left
    @CurrentDictStack = Array.new
    if ! @CurrentDictStack
      count = 0
      ObjectSpace.each_object { count += 1 }
      debug "#{count} objects"
      ObjectSpace.garbage_collect
      sleep 5
      count = 0
      ObjectSpace.each_object { count += 1 }
      debug "#{count} objects"
      @CurrentDictStack = Array.new
      exit unless @CurrentDictStack
    end
    debug "init: #{object_id} #{@CurrentDictStack.object_id}"
  end
# end-of-code

After a certain amount of processing this process dies, first indicating
about 93000 objects, 5 seconds later some 60000. The process is about 11 Mb
in size. Different machines, differnet libc's and different Linux kernels.
Ruby 1.6.8 out of the box, no extensions of my own, only extension not in
ruby core is REXML-2.5.7.


It runs fine under 1.8.0, so it's not a project stopper, but I'm of course
curious.

Cheers,
