EXC_BAD_ACCESS in xcode 8.3 while trying some filters

[mahdidham]

Looks like i have same issues with this stackoverflow issue with different case, maybe. I use ShiTomasiFeatureDetector() filter and got an error lldb (EXC_BAD_ACCESS code=2, code=1), in this instance:

the code addressed in pipeline.swift line 26, 39, 72

I update my code, so here's my code in ViewController.swift:

import UIKit
import CoreImage
import GPUImage
import AVFoundation
import QuartzCore

class ViewController: UIViewController {

    @IBOutlet var filterView: RenderView?
    var videoCamera: Camera?    

    required init(coder aDecoder: NSCoder) {
        do {
            videoCamera = try Camera(sessionPreset: AVCaptureSessionPreset640x480, location: .backFacing)
            videoCamera!.runBenchmark = true
        } catch {
            videoCamera = nil
            print("Couldn't initialize camera with error: \(error)")
        }
        super.init(coder: aDecoder)!
    }

    // declare filters and crosshairs
    var shiTomasiFilter = ShiTomasiFeatureDetector()
    lazy var crosshairGenerator: CrosshairGenerator = {
        let generator = CrosshairGenerator(size:Size(width:480, height:640))
        generator.crosshairWidth = 15.0
        return generator
    }()
    let blendFilter = AlphaBlend()

    override func viewDidLoad() {
        super.viewDidLoad()

        //  re-declare camera using guard-statement
        guard let videoCamera = videoCamera else {
            let errorAlertController = UIAlertController(title: NSLocalizedString("Error", comment: "Error"), message: "Couldn't initialize camera", preferredStyle: .alert)
            errorAlertController.addAction(UIAlertAction(title: NSLocalizedString("OK", comment: "OK"), style: .default, handler: nil))
            self.present(errorAlertController, animated: true, completion: nil)
            return
        }

        if let view = self.filterView {
            //  gettin' corners
            shiTomasiFilter.cornersDetectedCallback = {
                corners in self.crosshairGenerator.renderCrosshairs(corners)
            }
            shiTomasiFilter.threshold = 0.1

            videoCamera --> shiTomasiFilter
            crosshairGenerator --> blendFilter

            videoCamera --> blendFilter --> view

            videoCamera.startCapture()
        }

    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

}

Any suggestions?

Note: i use iphone SE and still in iOS 9.3 Is it have the same issue like https://github.com/BradLarson/GPUImage/issues/2022#issuecomment-118943746 ? Different framework but maybe still same issue.

All you have to do is check your identity inspector on your left (utilities bar), check whether class and module use 'RenderView' class and GPUImage modules or not.
