Well the inevitable suspicion is that you're not handling
memory-allocation for the string correctly - perhaps it's being freed
twice on server-side (once by you, and once by the ORB), or perhaps
you're not creating it in such a way that the ORB is able to free it
correctly.

I think we could do with seeing your server code which creates struct
and string and returns it, and the IDL for the method of interest.
