Hi Sai-Lai,

I've done the promised testing of omniORB2.2.0 under egcs on Linux.
Unfortunately, results are bad. Only thread examples and eg1 work.
Other examples were failed both with shared and static libraries
(ofcause, standard libraries i.e. libc (glibc-2.0.5c) and libpthread
(glibc-linuxthreads-2.0.5) are shared). I tried to debug eg2_impl but
unsuccessfully. Below there is a *strange* gdb output (client was run
on other computer, I marked actions related to client with *****).

I am curious about such gdb output, I have no starting point for
further debugging and I cannot say is this caused by egcs or omniORB
bug :-(. 

Well, I'll wait for upcoming new release and then I'll try to look at it
more closely. Below I put a summary of omniORB2.2.0 test results on
platforms available to me.
