Subject: OpenStruct, OpenObject both seg fault, this does not, anything wrong?


Ok, I am using 1.8.6 p110 with rails 1.2.5 and I use alot of
OpenStructs.
Well, it seg faults pretty regularly:

>> 0.upto(100) {|n| member.driver_process_member}
> /usr/lib/ruby/1.8/ostruct.rb:75: [BUG] Segmentation fault
> ruby 1.8.6 (2007-09-23) [i686-linux]


So I tried ruby 1.8.5, same thing.
So I tried OpenObject in the facets lib, seg faults in a different
place now:

>> member = Account.get(6).member;0.upto(100) {|n| member.driver_process_member}
/usr/lib/ruby/gems/1.8/gems/facets-2.1.1/lib/more/facets/openobject.rb:
183: [BUG] Segmentation fault
ruby 1.8.5 (2006-08-25) [i686-linux]

class HashDot < Hash
  def method_missing(sym, arg=nil)
    type = sym.to_s[-1,1]
    key = sym.to_s.sub(/[=?!]$/,'').to_sym
    if type == "="
      self[key] = arg
      return self[key]
    else
      return self[key]
    end
  end
end

So I created this minimalist class that extends hash, and it does not
segfault.
The questions are:
- how to figure out what's wrong with OpenStruct (I am not a gdb guy
but could follow instructions)
- why is the source for OpenStruct and OpenObject so complicated
(compared to HashDot)?
