bug in videoio crash while releasing capture

[fogelton]

• OpenCV => 4.0.1
• Operating System / Platform => Windows 7 64 Bit
• Compiler => Visual Studio 2017

when calling capture release, sometimes it crashes when the app is going to quit and the debugger stops in file cap_dshow.cpp, the problem is that it happens only from time to time, hard to reproduce. When the release is called without app quitting, it is OK all the time. Some resources are already deleted?

videoDevice::~videoDevice(){
    if(setupStarted){ DebugPrintOut("\nSETUP: Disconnecting device %i\n", myID); }
    else{
        if(sgCallback){
            sgCallback->Release();
            delete sgCallback;
        }
        return;
    }

    HRESULT HR = NOERROR;

    //Stop the callback and free it
    if( (sgCallback) && (pGrabber) )
    {
        pGrabber->SetCallback(NULL, 1);
        DebugPrintOut("SETUP: freeing Grabber Callback\n");
-->        sgCallback->Release();
