[omniORB] Debug Assertion Failed! Problems with 2.8.0 and Visual C++.

[Mike Bendickson]

Oops, I was using the debug libraries initially.  I tried the release
versions when I was in "try anything" mode.  Going back to the debug
libraries, the client and server appear to start correctly.  The client
displays the:

    I said,"Hello!".  The Object said,"Hello!"

message, then I get the 2 debug assertion failed messages.

Debug Assertion Failed!

 Program: ...
File: dbgheap.c
Line: 1011

 Expression: _CrtlsValidHeapPointer(pUserData)

Doing a release build, everything seems to run correctly if I execute the
client and server from the VC++ IDE.  If I try to run the client from a DOS
window I get an exception 0, 1.  UNKNOWN, NOT_COMPLETED?  I'm still
concerned about the debug assertion failures.

Is it possible that I have a conflict with the older version of omniORB on
my system?  I renamed the old directory and took it out of my path.  I don't
see how anything could be using it, but would that cause this type of
behavior?

-Mike
