We found several crash caused by SVProgressHUD in the daily log. But so far we could not figure out the reproduce procedure. So I just post the crash stack here and hope someone could help to identify the root cause. Thanks.(Model: iPhone5s iOS 8.1.2)

Please more details: Which Version of SVProgressHUD? Have you tried the latest beta? And nonetheless I need some more details, the stack trace is a start, but does not help at the moment.

I checked further. There is no access to NSArray in updateBlurBounds, in addition the key gaussianBlur is not used in this project.

we got the same issue. And the source code was downloaded from master at 2016.2.25.

 UIVisualEffectView *effectView = [[UIVisualEffectView alloc] initWithEffect:blurEffect];
 effectView.frame = self.bounds; // crash at this line

This crash is very rare. We saw the same stack trace in the crash log when using code above and it seems iOS 8 only. Maybe it's a system bug.
@simpleease Can you reproduce it?

I also think this is a system crash. There must be something happen in private classes such as _UIVisualEffectBackdropView. I tried very hard when this bug was reported, but I was not able to reproduce ...

I was not able to reproduce ... And this kind of crash logs were not received since then on.
Maybe it's a system bug...
