[tao-users] Re: crash with Visibroker 4.1 client
gu...@tvratings.com
reference generated by a Visibroker server (at which moment the TAO
process is now the client), we get a crash in Endpoint.i, Line 14.
It doesn't matter which program we use, it could be a TAO example
program where one part is developed in Visibroker.
If the error is not with TAO, it would at least be an improvement to
TAO to throw an exception indicating the problem in this scenario.
If there is nothing wrong with TAO, could you provide suggestions as
to where I should look next?
Here is an example run in dbx with -ORBDebugLevel 10:
