Subject: find some error with exception

run following script
---------------------------------------------
def foo(i)
    foo(i+1)
end
def main1
    begin
        foo(1)
    rescue
        puts $!.backtrace.join("\n")
    end
end

def main2
    begin
        foo(1)
    rescue
        puts $!.backtrace.join("\n")
    end
end

main1
main2
----------------------------------------------
this will has to "stack too deep" error at DIFFERENT line of the script
but the result will be
===========================
mm.rb:2:in `foo'
mm.rb:2:in `foo'
mm.rb:8:in `main1'
mm.rb:22
mm.rb:2:in `foo'
mm.rb:2:in `foo'
mm.rb:8:in `main1'
mm.rb:22
===========================
both show the 1st error position
this error should be correct
