Hello. When looking at the quartz.dll sources noticed in the filtergraph.c the
following:

static HRESULT WINAPI GraphBuilder_Connect(IGraphBuilder *iface,
					   IPin *ppinOut,
					   IPin *ppinIn) 
{
...

    hr = IPin_QueryPinInfo(ppinIn, &PinInfo); // line 695 - DL
    if (FAILED(hr))
       return hr;

    hr = IBaseFilter_GetClassID(PinInfo.pFilter, &FilterCLSID);
    if (FAILED(hr)) // if it fails
       return hr; // the function will return without releasing the filter
pointed by PinInfo.pFilter - DL
     

...
}
