Hello

I have recently upgraded IBO library to 5.2.0.7 (the latest version).
Everything works great except one customer environment. There is MS
Terminal Server where application compiled with latest IBO returns
following exception after connecting to the Firebird server [2.5.1.26266] :

ISC ERROR CODE:335544648

ISC ERROR MESSAGE:
unknown ISC error 0

I did some searching and found that this error code represents following
error:

335544648 conn_lost Connection lost to pipe server

I haven't noticed any similar behavior elsewhere.

Below is attached call stack from EurekaLog.
Maybe someone will be able to suggest something how to find the cause of
the exception...

Thanks
Marcin
