Subject Re: [IBO] Is this an IBO bug?
Author Michel LE CLEZIO

I don't beleive it's an IBO BUG.I Don't think DSAService.exe is a IBO or Firebird tools….
Maybe you need to upgrade some drivers …

Why not try to use the last IBO version ?

I hoppe you will find a solution.

Hi –


I use IBO with Delphi XE in a Windows service application.


This bug has been reported to me a handful times, but I can’t reproduce it. Stack trace below.


It happens when opening a TIBOQuery.


Although it happens during memory allocation, there does not seem to any abnormal memory consumption.


Is it a known IBO bug? Thanks for any help.
