Crash on iOS11 on devices with 1 GB RAM

I experience repeatable crashes when taking a series of pictures using the camera preview. The issue is present on iPhone devices with 1GB of RAM, such as the iPhone 6 or iPhone 6 Plus, and it has arose after the introduction of iOS11.

Not sure but it can be the same or related to #200.

I do take pictures normally:

window.CameraPreview.takePicture(this.photoSize, (imageFile) => {
    this.onPictureTaken(imageFile);
}, (error) => {
   console.log("error", error);
});
}, false);

onPictureTaken simply upload the photo to our server.

The crash happens after 5 to 10 pictures taken in rapid succession. ~I suspect that the OS is simply killing the app because of too high memory usage.~

Can you help me? Is there something that you need to debug the issue? Thank you very much

Update:

Debugging on Xcode is not helpful at all because the app crashes without any stack trace. I am not very expert in those stuffs but I am quite sure that the app crashes on this line:

CGImageRef finalImage = [self.cameraRenderController.ciContext createCGImage:finalCImage fromRect:finalCImage.extent];

in CameraPreview.m. I can confirm that the crashes happen when trying to take pictures in a rapid succession, tapping multiple times on the screen and only after a few pictures taken.

Any help would be really appreciated!
