odd stack error

Roger Pack

3/14/2008 4:10:00 PM

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
