Bug #5719: Hash::[] can't handle 100000+ args

ruby -v: -


I couldn't pin down an exact size for when/how this occurs, but I have code that was creating hashes just fine with Hash::[] with 300k+ arguments.

irb(main):056:0> (0...140000).map { |n| [:a, n] }.tap { |a| Hash[*a] }.size
SystemStackError: stack level too deep
	from /Users/qrush/.rbenv/versions/1.9.3-p0/lib/ruby/1.9.1/irb/workspace.rb:80
Maybe IRB bug!
irb(main):057:0> (0...130000).map { |n| [:a, n] }.tap { |a| Hash[*a] }.size
=> 130000
