memory leak in VectorOutput ?

[terryleetracymc]

in the source code: src/essentia/streaming/algorithms/vectoroutput.h

class VectorOutput : public Algorithm { protected: Sink _data; std::vector* _v;

public: VectorOutput(std::vector* v = 0) : Algorithm(), _v(v) { setName("VectorOutput"); declareInput(_data, 1, "data", "the input data"); }

~VectorOutput() { // _v not release ? *### if (!_v && _v->size()){ std::vector().swap(_v); }** }

I find memory leak when i use EasyLoader & MonoLoader with standard mode but not AudioLoader
