[omniORB] Process on Win32 crash while calling _this()

[M300_林錦龍處長]

Hi, all

Sorry to pollute traffic because I post source code.

At the beginning, I wanted to write a CosNotification Push Consumer, but the
process was always down on Win32. And then I ported to Linux and found this
program was OK; so I reduced my program to minimum to find out what
happened. This minimum program is like ECHO sample, I just modified some
statements.

The problem is, if main() constructs PushConsumer_i, the process crash when
calling _this(), if main() constructs Echo_i(from ECHO sample) instead of
PushConsumer_i, it's OK. The only difference is, if  main() constructs
PushConsumer_i, it must link COS_400rt runtime.

I'm supperised because it is quite simple beyond my imagination.

** My Env. **
omniORB 4 (Win32 and Linux)
Microsoft Visual C++ 6, SP5
Program Setting: Win32 Release, Use MFC in a shared DLL,
Runtime:
omniORB400_rt.dll, omnithread30_rt.dll, COS400_rt.dll

To Duncan,
Will this be the side effect by COS runtime (COS400_rt.dll)?

Thank you very much!

Best Regards,
Edward
