Details:

Attached is sample code which runs correctly under pnet-0.7.2 and 6.2. 
However, pnet2ms produces various exceptions, evidently because Dispose() is
being called on a null object. Pseudocode:

public string fail_function()
{
  using (RegistryKey rk = Registry.LocalMachine.OpenSubKey("some non-existent
key"))
  {
    if (rk!=null) do something // rk is null
  }

  return "something";
}

After running pnet2ms, the function gets a SystemExecutionEngineException,
but this may vary.  Seems like the problem is that the "using" section runs
Dispose() on the
null object rk.
