The latest omniORB 4.0.3 binaries are built with Visual C++ 6.0.  These
binaries will not work with Visual C++ 7.1 - you need to rebuild omniORB
from source.

[Duncan, are there plans to release VC7.1 binaries at some stage?  It seems
to be becoming more popular.  I've added my name to the volunteer list on
the wiki in case you need these to be contributed].

Yes, this is because the omniORB DLLs use the memory allocation functions in
the VC6 runtime library (MSVCRT.DLL / MSVCRTD.DLL), whereas your program
would be using the memory allocation functions in the VC7.1 runtime library
(MSVCR71.DLL / MSVCR71D.DLL).  Memory allocated with one of these four DLLs
must be deallocated with the same DLL.

Yes.
