QT Creator open Disassembler view before breakpoint



  • Hi, Anybody can tell me why the QT Creator open Disassembler view before run into the first breakpoint in debug mode? thanks.

    //it's weird. when I run the program in debug mode, QT creator, sometimes, it shows the assert warning. but if I run the program not in debug mode, it works well.

    And every time I start the program in debug mode, before stopping at first break point, QT Creator must shows a disassembler view.

  • Hello,

    Perhaps do you have a data breakpoint in your list of breakpoints ?



  • No, I am not set a data breakpoint, in fact, I don't know how to what is data breakpoint in QT Creator.


  • Moderators

    @samzhcs1 Do you use a debug or release build to debug?
    Where did you put the break-point?
