Since iOS 9.3, loading PDF data into a UIWebView produces the following log:
"objc[1369]: UIPDFPageRenderOperation object <address> overreleased while already deallocating; break on objc_overrelease_during_dealloc_error to debug"

Steps to Reproduce:
1. Create an new iOS app with a UIWebView
2. Load a PDF content into a NSData variable
3. Use -[loadData:MIMEType:textEncodingName:baseURL:] to load the PDF data into the webview

Expected Results:
No logs appear in the debug console.

Actual Results:
The message "objc[1369]: UIPDFPageRenderOperation object <address> overreleased while already deallocating; break on objc_overrelease_during_dealloc_error to debug" appear in the console.

Regression:
Did not occur with iOS version under 9.3.

Notes:
Attached is a minimal test project presenting the issue. Just run the project and look at the logs.

Crash when we scroll really fast on PDF rendered in WKwebView

I even get a crash if I scroll really fast on the PDF rendered in the WKWebView. This crash is happens when the UIGestureRecognizers are being deallocated inside [UIPDFView dealloc ] Unable to find the original issue for this

Wish there was a way to add image to be able to provide teh exact stack trace.
