Thanks in advance

Hi,

Looks like you have a pointer issue.

Did you check them in your application ?
Are you doing some multi-threading ?

[Ketan__Patel__0011]

@SGaist

Yes
My Application Is Multi Threading Based

[SGaist]

Then the first thing to do is to check your ressources access especially if you are sharing them across threads.

RptCrossTabObject::visibleRowCount

Check this function probably array out of bound access is happening

Yes I am using or sharing my UI components in my thread functions

You must not modify the GUI outside the main thread!
