ERROR_CGDataProvider_BufferIsNotReadable crash

We're also finding this a lot in Crashlytics for 11.2.x (ONLY).

If you click "View all sessions", do you see a lot of "613: CFNetwork internal error" keys? I have a feeling this is related to fetching image data when network connectivity isn't that great.

We are using Xcode 9.2 and also SDWebImage in a rather image-heavy app. I have yet to reproduce this (nor our QA team). It's not terribly often this happens, but we'd sure like to know why and how to avoid it.

I'm receiving reports of this error still on 11.2.5 specifically from 7 Plus.

The code that fails:

extension UIImage {
    func renderResizedImage (newWidth: CGFloat) -> UIImage? {
        let scale = newWidth / self.size.width
        let newHeight = self.size.height * scale
        let newSize = CGSize(width: newWidth, height: newHeight)
     
        let renderer = UIGraphicsImageRenderer(size: newSize)
     
        let image = renderer.image { (context) in
            self.draw(in: CGRect(origin: CGPoint(x: 0, y: 0), size: newSize))
        }
        return image
    }
}

Line 10 produces error with the following stack trace (line UIImage+.swift:51 represents line 10 from the above code listing):

I'm also still seeing this on "11.2.x" including the latest 11.2.5. Hundreds per day on a popular image-heavy app. Exclusivly when low on RAM.

Same here. We build a news feed application which contains many images. This crash randomlly(our DAU 10 Million, crash 2K per day, 2%%) only on iOS 11.2.0- 11.2.5 user both on iPhone/iPod Touch/iPad...Any walkaround or solution for this ?

We use Fabric to collect the crash log, here is one sample :

I get this when I attempt to CGContextDrawImage a CGImage that's backing a UIImage.

I've hit this in the debugger a few times now.

When I attempt to display the UIImage in the debugger, I see the following additional lines then added to the console:

2018-02-23 18:19:00.963013-0500 Photobooth[1455:1000835] handle_error:351: zlib error

(lldb)

I have a same issue :3

Same here on iOS 10.3.3-11.2.5. I haven't been able to reproduce it yet. Any clues ?

I got the same question. When I try to save a image to filePath.

iOS 11.2.6, iPhone 8Plus

Here is my code :

UIImage* quickFilteredImage = UIGraphicsGetImageFromCurrentImageContext();

UIGraphicsEndImageContext();

/

CGImageRelease(imageLeft);

CGImageRelease(imageRight);

/

CGImageRelease([warpLeft CGImage]);

CGImageRelease([warpRight CGImage]);

if (savePath != nil && quickFilteredImage) {

[UIImageJPEGRepresentation(quickFilteredImage, 0.9) writeToFile:savePath

options:NSDataWritingAtomic

error:NULL];

return nil;

}

return quickFilteredImage;

// ============================================================================================================

I got this crash.

How can I contact you ? mail. The same as me, I can reproduce it.

Any Progress?

Someone posted this SO. https://stackoverflow.com/questions/49429715/core-graphics-quartz-2d-image-resizing-crashes

but no answer yet. I think this is a memory issue, the data deallocated, since there are no strong refrence to it. The lifetime of image data only valid within the function, so OS will deallocate it if it needs.

this error also happend in 11.3 iphone8.
