        I have an XCUITest and in the course of the test, in tearDown for eg. I call the leaks tool on the application and generate a memgraph.

         

        % leaks App_Name --outputGraph=~/Desktop/Foo.memgraph

         

        Before launching the application, I set MallocStackLogging so that the backtraces are present.

         

        XCUIApplication *app = [[XCUIApplication alloc] init];  
        NSMutableDictionary *launEnv = [app.launchEnvironment mutableCopy];
        [launEnv setObject:@"1" forKey:@"MallocStackLoggingNoCompact"];
        app.launchEnvironment = launEnv;



        If I pause the application process in the course of the test, and open the Memory Graph Debugger, the entire call trace is present for a leak.

        On calling the above command, the leaks file is found to contain the call trace however the memgraph only contains

        0 malloc_zone_calloc
        49 _main_thread


        for all objects. Also, calling the leaks command provides the following output:
