Subscribe of Rx yields an IDisposable - but it is not marked as not disposed

This problem only occurs, when return value of Subscribe() is not stored in a local variable.

[BADF00D]

I was able to reproduce the problem with the following code:

using System.IO;
namespace DisFixerTest.MethodCall {
    class MethodCallWithoutSavingReturnValue {
        public MethodCallWithoutSavingReturnValue() {
            Create();
        }
        private MemoryStream Create() {
            return new MemoryStream();
        }
    }

}
