Folks,<br><br>I was doing testing of some modifications that I did in ibiou and suddenly I got a crash in ibbus.<br><br>I am not sure whether it happened due to some changes that I did in ibiou (because I can't see any ibiou functions in the stack trace).<br>
Can any one point to what was the cause.<br>I am using 1807 revision, So there are chances that it might have got fixed.<br><br>Below is the stack trace:--<br><br>*********************************************************************************************************************************************<br>
