How can I see memory leaks on MacOS Big Sur using CLion?

Question

I don't know how can I see memory leaks using CLion on MacOS Big Sur using CLion and I've tried these things:

1. Valgrind - which is not compatible with Big Sur

2. Leak Sanitizer from Clang - which apparently isn't compatible with MacOS according to a support guy from CLion

3. Inside CLion, I've written in CMakeLists.txt this command:

      set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -fsanitize=address -g")
   

   then I've written in preferences menu -> sanitizers in Address sanitizer section:

      detect_stack_use_after_return=1
   

   Based on CLion support page, they said that Leak Sanitizer is included in Address sanitizer.

Answer 1

Assuming you have installed the xcode command line developer tools, open a terminal window in CLion and try the following command, where programname is the name of the program you are building:

leaks -atExit -- cmake-build-debug/programname

You get output something like this:

leaks Report Version: 4.0
Process 69522: 214 nodes malloced for 21 KB
Process 69522: 1 leak for 1008 total leaked bytes.

    1 (1008 bytes) ROOT LEAK: 0x14c6067f0 [1008]
