What are the causes of abrupt termination of a program with Qt6?



  • Hello, I have been working on a two window project for some time and just finished editing the code for the first window. But, when I compile, the IDE writes an error message saying "Gross program shutdown at 19:36:39", I don't know why my program abruptly terminated, this is the first time that This happens to me, however, no coding error was generated, not even warnings. I am writing this post because I would like to know (if any) the most common causes of a program crashing with Qt6 (I use the QtCreator IDE), not for my project, but in the general case of Qt projects and how to solve these problems.

    Thank you for your attention!

    Hi
    The normal way to find out what is going on is using the debugger.
    So compile the app In debug mode and start it.

    When it crashes you should be able to see what it was doing in the call stack.
    The call stack is the area under the editor window when starting in debug mode

    As you can see it shows where the program was running.
    The function list.

    This should give a hint as to why it does crash.
