Ok, here is symbolization using the information available in the snapshot: ``` Crc32.compute BinaryReaderImpl.readFrame FrameHelper.framesFromBytes FrameIoHelper.framesFromFile _SuspendState._createAsyncStarCallback. _RootZone.runUnary _FutureListener.handleValue _Future._propagateToListeners.handleValueCallback _Future._propagateToListeners _Future._completeWithResultOf _Future._propagateToListeners.handleWhenCompleteCallback. _RootZone.runUnary _FutureListener.handleValue _Future._propagateToListeners.handleValueCallback _Future._propagateToListeners _Future._completeWithValue _Future._asyncCompleteWithValue. _microtaskLoop...
