应用程序在glDrawArrays上崩溃（GL_TRIANGLE_STRIP，0,4）;在GPUImageFilter中

Question

如果我尝试将模糊区域从圆形更改为矩形并且矩形更改为圆形，我会在此行上获得此错误EXE_BAD_ACCESS“glDrawArrays（GL_TRIANGLE_STRIP，0,4）;” 请任何人建议我做什么？

-(IBAction) handleTapToFocus:(UITapGestureRecognizer *)tgr

if (hasBlur)
{
    if (!isSquareBlurr)
    {
        blurFilter = nil;
        [self showBlurOverlay:NO];
        hasBlur = NO;
        [self prepareFilter];

        [focusImgView setImage:[UIImage imageNamed:@"rect_focus.png"]];

        blurFilter = [[GPUImageGaussianSelectiveBlurFilter alloc] initwithrect];
        [(GPUImageGaussianSelectiveBlurFilter*)blurFilter setExcludeCircleRadius:80.0/320.0];
        [(GPUImageGaussianSelectiveBlurFilter*)blurFilter setExcludeCirclePoint:CGPointMake(0.5f, 0.5f)];
        [(GPUImageGaussianSelectiveBlurFilter*)blurFilter setAspectRatio:1.0f];
        focusImgView.hidden = FALSE;

        if ([stillCamera cameraPosition] == AVCaptureDevicePositionFront)
        {
            location.x = frameSize.width - location.x;
        }
        pointOfInterest = CGPointMake(location.y / frameSize.height, 1.f - (location.x / frameSize.width));
        if ([device isFocusPointOfInterestSupported] && [device isFocusModeSupported:AVCaptureFocusModeAutoFocus])
        {
            NSError *error;
            if ([device lockForConfiguration:&error])
            {
                [device setFocusPointOfInterest:pointOfInterest];

                [device setFocusMode:AVCaptureFocusModeAutoFocus];

                if([device isExposurePointOfInterestSupported] && [device isExposureModeSupported:AVCaptureExposureModeContinuousAutoExposure])
                {
                    [device setExposurePointOfInterest:pointOfInterest];
                    [device setExposureMode:AVCaptureExposureModeContinuousAutoExposure];
                }

                self.focusView.center = [tgr locationInView:self.view];
                self.focusView.alpha = 1;

                [UIView animateWithDuration:0.5 delay:0.5 options:0 animations:^{
                    self.focusView.alpha = 0;
                } completion:nil];

                [device unlockForConfiguration];
            }
            else
            {
                NSLog(@"ERROR = %@", error);
            }
        }
    }
}
}

这在glDrawArrays崩溃（GL_TRIANGLE_STRIP，0,4）; in - （void）renderToTextureWithVertices：（const GLfloat *）vertices textureCoordinates：（const GLfloat *）textureCoordinates sourceTexture：（GLuint）sourceTexture; GPUImageTwoPassFilter.m

的方法
