GIFReadPlugin crashes

Originator:garrett.moon
Number:rdar://30196911 Date Originated:1/25/2017
Status: Resolved:
Product: Product Version:
Classification:Crash Reproducible:
 
Summary:
We're seeing rare crashes in our app when viewing GIFs. I've never been able to reproduce, however it is one of the top crashes in our app currently. I've attached a sample. Of note, the reason I'm filing a radar is this isn't the only GIF library that appears to have this issue, it also seems to occur in FLAnimatedImage https://github.com/Flipboard/FLAnimatedImage/issues/159

We've also seen the same issue with a completely separate code path (I'm mentioning this in hopes that it indicates an issue with GIFReadPlugin not our code though that obviously can't be ruled out).

The crash I attached's source is available here: https://github.com/pinterest/PINRemoteImage/blob/master/Pod/Classes/PINAnimatedImageManager.m#L397

I wrote it, it's very ugly, I'm very sorry :D
