Hi,

I run Arch and just upgraded to ruby-1.8.7_p22 but it seems the string 
issue is partially fixed.

irb(main):001:0> str = "A"*(2**16); nil
=> nil
irb(main):002:0> while true
irb(main):003:1> str << str
irb(main):004:1> end
(irb):3: [BUG] Segmentation fault
ruby 1.8.7 (2008-06-20 patchlevel 22) [i686-linux]

Aborted

While the following works fine:
irb(main):001:0> str = "A"*(2**16); nil
=> nil
irb(main):002:0> while true
irb(main):003:1> str = str+str
irb(main):004:1> end
ArgumentError: negative string size (or size too big)
        from (irb):3:in `+'
        from (irb):3
        from :0


I have another computer with Ubuntu and ruby 1.8.6 in which both cases 
worked fine.
