Problem when invoking name service from Visibroker

[Sai-Lai Lo]

Hi! I hope when you say "omniBroker", you mean omniORB :-)

The problem you have experienced is caused by a bug in omniidl2
(omniORB_2.2.0):

The stub code to unmarshal user exception allocates the
wrong size buffer for the repository ID string. This causes marshalling
failures when the exception has a #pragma prefix defined.

This bug has been reported by several users.

The following patch to omniidl2 fix the problem:
