[1.9] Wrong block args handing
------------------------------

                 Key: JRUBY-4638
                 URL: http://jira.codehaus.org/browse/JRUBY-4638
             Project: JRuby
          Issue Type: Bug
          Components: Ruby 1.9
    Affects Versions: JRuby 1.4
            Reporter: Vladimir Sizikov
            Assignee: Thomas E Enebo


Consider the following:

{noformat}
ruby -e "order = lambda {|x| p x; x[0] <=> x[1]}; p [1,2,3].max(&order)"
{noformat}

MRI produces:
{noformat}
[2, 1]
[3, 2]
3
{noformat}

JRuby produces totally wrong results:

{noformat}
jruby --1.9 -e "order = lambda {|x| p x; x[0] <=> x[1]}; p [1,2,3].max(&order)"
2
3
1
{noformat}

The result of max is *1*, which is totally wrong, and the block parameters are 
wrong.
