[mono] thread not been gc when method execute end.

[srxqds]

we have the test code show below:

public void TestGetSingleton()
{
    TestGetSingletonThreadSafe();

    void TestGetSingletonThreadSafe()
    {
        void MyThreadMethod()
        {
            FModuleManager.Get();
        }

        Thread thread = new Thread(new ThreadStart(MyThreadMethod));

        thread.Start();
        FModuleManager.Get();
        thread.Join();

    }
}

// and the FModuleManager code:
public partial class FModuleManager : ScriptingWrapperOfType
{
    [MethodImpl(MethodImplOptions.InternalCall)]
    public static extern FModuleManager Get();
}

we have usemono_gc_walk_heap analyze the FModuleManager not been gc, No other code references.

gc_heap_walk the alc Engine_1(000002B71AF875A0) has object(UnrealEngine.FModuleManager) 000002B77455B060 live

it seems not free the thread stack??

[hez2010]

try changing the line Thread thread = new Thread(new ThreadStart(MyThreadMethod)); to using Thread thread = new Thread(new ThreadStart(MyThreadMethod));

[srxqds]

try changing the line Thread thread = new Thread(new ThreadStart(MyThreadMethod)); to using Thread thread = new Thread(new ThreadStart(MyThreadMethod));

the Thread class not implemented System.IDisposable
