Memory leaks

[v71]

Just creating the PhysicsCommon causes a massive amounts of memory leakage

What am I doing wrong ?

[DanielChappuis]

Can I ask you what are those logs? Where are they coming from?

[v71]

Ok, first of all sorry if i misplaced my post, i left another post in the discussion forums, weeks ago, and looks like nobody have the same issues we are having. For a project of my company , we are evaluating 3rd party 3d libs. The logs come from the visual studio 2022 debugger. To reproduce it , create a blank console application in debug mode

[DanielChappuis]

Do you have an error message somewhere? Can you paste your complete code here? Can you also try to compile the "Hello World" application and see if you have the same issue?

[v71]

This is the most basic things we wrote visual studio 2022 , c++17. also we noticed 12 warnings related to uninitialized variables in various classes ( yes we tried the hello world app )

Before you ask, we also tried to move the physicscommon class out of main, allocate it using 'new' and freeing, but the problems still persists

[DanielChappuis]

I am not familiar with _CrtDumpMemoryLeaks() (I only use valgrind on Linux to check this) but in your code when this function is called the memory as not been released yet (the call is before the return statement). In your pointer version of that code, did you call _CrtDumpMemoryLeaks() after the delete statement?

Is this tool able to tell where in the code the leaks are happening (like valgrind)?

[v71]

The visual studio memory leak detector does not give the line(s) where the offending code is located, yes , the code structure stays the same, , no matter how you instantiate physicscommon, the leak detector always reports those memory leaks

[DanielChappuis]

yes , the code structure stays the same, , no matter how you instantiate physicscommon, the leak detector always reports those memory leaks

Yes but I mean you are aware that in your code example above you test for leaks BEFORE releasing memory and therefore it's normal to find leaks in this situation. In your code above the destructor of the "physicsCommon" instance has not been called when you call _CrtDumpMemoryLeaks(). The destructor is only call at the end of the main function. Can you confirm that your code above is wrong or is there something I misunderstand?

[v71]

The code above is correct, also there are some warnings

[v71]

Sorry , I forgot to mention that I use visual studio 2022 with my current language , ( italian ) , in the debugger windows you are seeing uninitialized variables along with class information

[DanielChappuis]

Hello. I took some time to investigate this. I am able to reproduce your results. I tried to break at the memory allocations with possible leaks. However, the only ones that I am able to break on, are allocations that are correctly released at the end. I tried to use two other different memory leak debuggers (valgrind and VLD) and they don't find any leak for the same example. I don't know if those results are part of the possible false positives of the CRT leak detection that are described here but I am not able to prove the memory leaks.

I don't have enough experience with the CRT memory leak detector of Visual Studio to go further. I will close this issue for the moment but feel free to let me know if you an any idea how to proceed to prove there are indeed memory leaks.
