Application stops working unexpectedly

[baluk]

From my code I get the error next after the destructor statement

delete ui;

. When I press F10 from the statement, I get the segmentation fault message.

[high_flyer]

you probably forgot to do ui = new <YourUIWidget>;

Post the whole backtrace.

Here I am attaching the image showing the debugger output. I can't see the option to copy the output. And I see the message

Lowest section in C:\Windows\system32\normaliz.dll is .text at 00401000

in the console after stopping the debugger.

So the crash happens when you are closing the application? Does the program work correctly until then?

[baluk]

yes exactly. the crash happens only when closing the app. Until then every thing works fine. Before It was running fine but when I added the above function my app started crashing. So I then removed the function but still the crash happens when closing the application.

My guess is that you have a double delete somewhere. You are deleting some object explicitly and then MainWindow destructor deletes it again.
