  • [SOLVED] Referenced data not displayed

    I am trying to debug some data that is held within a reference on the stack. However, I am not able to see the content of it in ozone. In my production project I get "<outofscope>" in the location. In the minimal example shown below I get the correct address, size and type; however I don't get any values displayed:


    OS: Windows 10 1909
    Compiler: ARMCC 6.6.3 with -O0
    Target: LPC1768
    Ozone Version: 3.22e

    The example code:

    C Source Code: Main.cpp

    1. //disable heap
    2. __asm(".global __use_no_heap\n\t");
    3. //disable argv handling with ARMCC6 with -O0
    4. __asm(".global __ARM_use_no_argv\n\t");
    5. struct Foo
    6. {
    7. int MyInt;
    8. bool MyBool;
    9. Foo() : MyInt(0), MyBool(false) {}
    10. };
    11. class Bar
    12. {
    13. public:
    14. void doSomething()
    15. {
    16. auto& currentData = myContainer[0];
    17. currentData.MyBool = !currentData.MyBool;
    18. currentData.MyInt++;
    19. }
    20. private:
    21. Foo myContainer[2];
    22. };
    23. extern "C" int main(void)
    24. {
    25. Bar bar;
    26. while(true)
    27. {
    28. bar.doSomething();
    29. }
    30. return 0;
    31. }

  • I also see a similar issue from time to time in version 3.22e on Linux x64.

    A global struct in my code that is not out of scope (address of fields are shown) shows empty values.

    I do not know yet the exact steps to reproduce this, but I have seen it very often.
