    This manifests itself in rescues as well:

def caller_in_eval
  eval(";raise 'w00t&#39;")
end

def method_with_block
&nbsp; begin
&nbsp; &nbsp; yield
&nbsp; rescue
&nbsp; &nbsp; p "method_with_block"

  end
end

method_with_block do
  begin
&nbsp; &nbsp; caller_in_eval
  rescue
&nbsp; &nbsp; p "calling m_w_b";
  end
end

You would expect to see "method_with_block" but instead get "calling m_w_b";
