Crash without "don't send"- why?

Hi.
What can cause application crash with out "don't send" dialog?

You cannot scale down the reason which cause crash but dont appear Dont Send dialog . Mostly when ur application crashes due to unhandled exceptions or deleting memory which is already deleted something like that may cause Window appear Dont send message box. Actually every programm when exited then it returns some value to OS, So OS then decide wether or not appear Dont Send dialog. if Your program smoothly closed then ur Os did not appear such dialog but when your program crashes and return some error code then OS displays that dialog.

The "don't send" dialog will not appear if you are running a debug version.

Yes,in debug- it's first chance exception- access violation.

thanks,all
