If the source code is in your possession begin with a developer build of the code and try to reproduce the issue stepping through the code leading up the crash, paying attention to the I/O requirements, for example if you're making remote API calls, is the data requirement of API being met as a result of the call prior to rendering the data. Crash dumps mean nothing to a third party without the source code but this is merely an assumption that such is happening based on the threads info.

I'm running into the exact same issue. I haven't been able to reproduce it yet. It has occured on iOS 10.x and 11.x.

we alse encountered the same crash,but it has occured on ios 11.2 or 11.2.1, and December 5 after the crash

Suspected the source code is data convert to image!!

+ (UIImage *) convertBitmapRGBA8ToUIImage:(unsigned char *) buffer

withWidth:(int) width

withHeight:(int) height

hasAlpha:(BOOL)hasAlpha{

UIImage *image = nil;

CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();

CFDataRef data = NULL;

CGImageRef cgImage = NULL;

CGDataProviderRef provider = NULL;

/

size_t bytesPerRow = 4 * width;

size_t componentsPerPix = 4;

size_t bitsPerPixel = 8;

CGBitmapInfo bitmapInfo = kCGBitmapByteOrderDefault | kCGImageAlphaLast;

data = CFDataCreate(kCFAllocatorDefault, buffer, width * height * componentsPerPix);

provider = CGDataProviderCreateWithCFData(data);

cgImage = CGImageCreate(width,

height,

bitsPerPixel,

bitsPerPixel * componentsPerPix,

bytesPerRow,

colorSpace,

bitmapInfo,

provider,

NULL,

NO,

kCGRenderingIntentDefault);

/

/

/

/

/

/

if (nil != cgImage) {

image = [UIImage imageWithCGImage:cgImage];

CGImageRelease(cgImage);

}

if (provider){

CGDataProviderRelease(provider);

}

if (data){

CFRelease(data);

}

CGColorSpaceRelease(colorSpace);

return image;

}

The same as me.

I'm seeing the same issue, too.

Seeing this too, it only seems to happen on iOS 11.2

I'm experiencing the same issue.

Is it crashing 100% of the time? Have you been able to reproduce it with an image you can share?

Thanks

We're experiencing the same issue—only users with iOS 11.2.0-5. I can't seem to reproduce it, either, but it's frequently coming up in our crash reports.

We are seeing this issue. It is happening on iOS 11.2 - 11.2.1.

Hello,

I have a crash once in every 1000 sessions on my app and I can't figure out what to do about it,

The crash looks quite the same as yours.

Is that an Apple iOS crash where I cant do anything about it?

I am using SDWebImage pod in my project, maybe it is that?

here is the crash log:

Same here and only on iOS 11. I haven't been able to reproduce it yet. Any clues ?

We are also experiencing this issue in 11.2. We are able to reproduce it rather consistently, but the specific image or line that is raising the exception is still something that I am tracking down. I know that a view controller is closed and I am logging this and other events around the crash. It seems like it could be a disposed image or a leak?

Hey, could you share the details of how you were able to reproduce it?

If you could share bits of code, or a sample image on github I guess I could also give a hand.

Same happens to me. lots of crash on iOS 11.2.X
