Summary iPad iOS Safari crashes when removing loading or rendering SVGs from the DOM

Created attachment 134806 [details] Incorrect file - don't use! Overview: A complete crash of safari occurs when removing an embed element from the DOM while the SVG contained in the embed element is still loading and rendering. It may seem like an edge case, but this issue occurs fairly frequently in a web app that we're developing. We need it to be fast and responsive and can't delay the users actions (which include clearing parts of the DOM which contain embedded SVG) as this will result in a poor user experience. Also, there doesn't seem to be a way of binding to a 'SVG has finished rendering' event (if one exists) for SVG rendered in embed tags. Steps to recreate (using the attached files) are: 1) Load the page on an iPad in Safari 2) Click on the load button (this will display some extra SVGs in the DOM) 3) Within about 150-300ms of the last click, click the remove button. This will remove all SVGs from the DOM by removing the embed elements. The crash will occur every time if removed within this time period. Actual Results: Safari crashes completely to the home screen with no user message Expected Results: The embed elements should be removed from the DOM without crashing safari Build Date & Platform: The bug is found using an iPad running iOS 5.1 using Safari (webkit version 534.46) Supporting materials: This is the log we get from iOS when the crash occurs Incident Identifier: F8C1A042-1B1B-419E-B649-08FECE6E2842 CrashReporter Key: c3bb0efec7add244f43eb200d8b512169ef1e78e Hardware Model: iPad2,1 Process: MobileSafari [474] Path: /Applications/MobileSafari.app/MobileSafari Identifier: MobileSafari Version: ???

If just mobile Safari is affected, please report bugs at: https://bugreport.apple.com/ You might also test your file with a latest nightly build of WebKit to see if it is a WebKit bug: http://nightly.webkit.org/ Greetings, Dirk

@Dirk, Thanks for the comment, it seems to be some sort of race condition during the load and removal of an SVG and since desktop versions of the browsers (I assume I'd need a desktop browser to try a nightly of webkit) are really fast with loading and rendering of SVG, it rather limits the window of operability for the race condition to occur. So I'm not sure if I'll be able to tell if it occurs using the latest nightlies! :) We should have an iPad 3 soon (which I'm guessing will have a later version of webkit with safari), so I'll be able to try that! I've lodged a separate bug already with apple, but I guess the webkit references in the stack trace lead me to believe that it is webkit related. (That and apple don't seem to ever give feedback to their bug reports!) Thanks! Andy.

Dirk is right - when there is no direct evidence that a bug you observe on iOS affects other platforms, it should go to <http://bugreport.apple.com>. > I've lodged a separate bug already with apple Please post the 8-digit bug number here.

Hey, the apple bug ID is: 11155336 I guess there are a couple of references to WebKit in the crashed thread's stack, but I can understand that it isn't really evidence of such that WebKit is to blame. Thanks, Andy.
