Anybody have any ideas as to what might be going on here? It yields a  
stack level too deep exception after like 15 method calls. Note that I  
do have one function call that is

large\_hash\_like\_20000\_members.each{|key, value| …}

Is that all going on the stack as an array, maybe?  
This is on OS X.  
Thanks!

This works fine for me on OS X and ruby 1.8.2:

def test

h = Hash.new  
1.upto(100\_000) do |i|  
h[i] = i  
end

puts h[100\_000]

h.each do |key, val|  
puts key, val  
end

end

test
