[omniORB] CORBA::Double type corrouption issue in python omniORB

[Amit]

Thanks Jhonny and Duncan,

    I will try the test, also I am going to run the server on x86 target and see how it behaves. So you guys might be right about it being an ACE TAO ARM problem. 
  If that is the case then is there a workaround you guys would suggest.
Regards,
Amit
