Ruby

A question about the test you added, nobu:

  def test_too_many_args_in_eval
    bug5720 = '[ruby-core:41520]'
    arg_string = (0...140000).to_a.join(", ")
    assert_raise(SystemStackError, bug5720) {eval "raise(#{arg_string})"}
  end

Why SystemStackError? Why isn't it ArgumentError, since raise does not take 140000 arguments?

In JRuby, we currently raise ArgumentError for this.

It occurs when pushing arguments onto the VM stack, before the arity check.
The check cannot be before it since there may be splats.
