Summary Either crash or 2 world leaks reported when visiting this website

Reported 2006-02-16 11:32:32 PST
I have tried around 10 times and I consistently get one of these three results when using the latest webkit (16th Feb). Note however that if I use the official Safari in 10.4.4 then there are never any problems. To get the results: 1-Star with no open windows (and I do not get reports of world leaks) 2-I go to http://www.animeclick.it/ 3-This redirects to http://animeclick.nipogames.com/index.php 4-When it has finished loading the page, close the window Then one of three things occur: 1-It crashes 2-It reports 2 world leaks (one was the JavaScript interpreter, I think, but I should check again) 3-Nothing happens. However if then I try again I consistently get result number 2 (the world leaks) If there is anything more I can add to help you understand this, please tell me.

I do not know if it helps, but after one of the crashes, this was the report Safari wanted to send to Apple: -------------------------------------------------- Date/Time: 2006-02-16 20:17:46.450 +0100 OS Version: 10.4.4 (Build 8G32) Report Version: 3 Command: Safari Path: /Applications/Safari.app/Contents/MacOS/Safari Parent: WindowServer [68] Version: 2.0.3 (417.8) Build Version: 1 Project Name: WebBrowser Source Version: 4170800 PID: 654 Thread: 0 Exception: EXC_BAD_ACCESS (0x0001) Codes: KERN_PROTECTION_FAILURE (0x0002) at 0x00000000 Thread 0 Crashed: 0 <<00000000>> 0x00000000 0 + 0 1 com.apple.WebCore 0x012cc340 WebCore::TimerBase::sharedTimerFired() + 112 2 com.apple.CoreFoundation 0x90770aec __CFRunLoopDoTimer + 184 3 com.apple.CoreFoundation 0x9075d464 __CFRunLoopRun + 1680 4 com.apple.CoreFoundation 0x9075ca18 CFRunLoopRunSpecific + 268 5 com.apple.HIToolbox 0x9318e1e0 RunCurrentEventLoopInMode + 264 6 com.apple.HIToolbox 0x9318d7ec ReceiveNextEventCommon + 244 7 com.apple.HIToolbox 0x9318d6e0 BlockUntilNextEventMatchingListInMode + 96 8 com.apple.AppKit 0x9368b104 _DPSNextEvent + 384 9 com.apple.AppKit 0x9368adc8 -[NSApplication nextEventMatchingMask:untilDate:inMode:dequeue:] + 116 10 com.apple.Safari 0x000072d4 0x1000 + 25300 11 com.apple.AppKit 0x9368730c -[NSApplication run] + 472 12 com.apple.AppKit 0x93777e68 NSApplicationMain + 452 13 com.apple.Safari 0x0005cfdc 0x1000 + 376796 14 com.apple.Safari 0x0005ce80 0x1000 + 376448 Thread 1: 0 libSystem.B.dylib 0x9000b208 mach_msg_trap + 8 1 libSystem.B.dylib 0x9000b15c mach_msg + 60 2 com.apple.CoreFoundation 0x9075d114 __CFRunLoopRun + 832 3 com.apple.CoreFoundation 0x9075ca18 CFRunLoopRunSpecific + 268 4 com.apple.Foundation 0x928f5664 -[NSRunLoop runMode:beforeDate:] + 172 5 com.apple.Foundation 0x928f559c -[NSRunLoop run] + 76 6 com.apple.WebKit 0x0036ce94 +[WebFileDatabase _syncLoop:] + 180 7 com.apple.Foundation 0x928e66d4 forkThreadForFunction + 108 8 libSystem.B.dylib 0x9002b200 _pthread_body + 96 Thread 2: 0 libSystem.B.dylib 0x9000b208 mach_msg_trap + 8 1 libSystem.B.dylib 0x9000b15c mach_msg + 60 2 com.apple.CoreFoundation 0x9075d114 __CFRunLoopRun + 832 3 com.apple.CoreFoundation 0x9075ca18 CFRunLoopRunSpecific + 268 4 com.apple.Foundation 0x9290db9c +[NSURLConnection(NSURLConnectionInternal) _resourceLoadLoop:] + 264 5 com.apple.Foundation 0x928e66d4 forkThreadForFunction + 108 6 libSystem.B.dylib 0x9002b200 _pthread_body + 96 Thread 3: 0 libSystem.B.dylib 0x9000b208 mach_msg_trap + 8 1 libSystem.B.dylib 0x9000b15c mach_msg + 60 2 com.apple.CoreFoundation 0x9075d114 __CFRunLoopRun + 832 3 com.apple.CoreFoundation 0x9075ca18 CFRunLoopRunSpecific + 268 4 com.apple.Foundation 0x9290ecdc +[NSURLCache _diskCacheSyncLoop:] + 152 5 com.apple.Foundation 0x928e66d4 forkThreadForFunction + 108 6 libSystem.B.dylib 0x9002b200 _pthread_body + 96 Thread 4: 0 libSystem.B.dylib 0x9001f20c select + 12 1 com.apple.CoreFoundation 0x9076f9a8 __CFSocketManager + 472 2 libSystem.B.dylib 0x9002b200 _pthread_body + 96 Thread 5: 0 libSystem.B.dylib 0x9002b8a8 semaphore_wait_signal_trap + 8 1 libSystem.B.dylib 0x9003001c pthread_cond_wait + 488 2 com.apple.Foundation 0x928ed840 -[NSConditionLock lockWhenCondition:] + 68 3 com.apple.Syndication 0x99cee50c -[AsyncDB _run:] + 192 4 com.apple.Foundation 0x928e66d4 forkThreadForFunction + 108 5 libSystem.B.dylib 0x9002b200 _pthread_body + 96 Thread 0 crashed with PPC Thread State 64: srr0: 0x0000000000000000 srr1: 0x000000004000f030 vrsave: 0x0000000000000000 cr: 0x42028222 xer: 0x0000000020000007 lr: 0x00000000012cc294 ctr: 0x0000000000000000 r0: 0x0000000000000000 r1: 0x00000000bfffe970 r2: 0x0000000000615050 r3: 0x00000000006929b0 r4: 0x0000000000000040 r5: 0x0000000000000029 r6: 0x00000000bfffe658 r7: 0x000000001845d5bd r8: 0x00000000006d0800 r9: 0x0000000000000000 r10: 0x00000000006d0700 r11: 0x0000000000000000 r12: 0x0000000000000000 r13: 0x0000000000000000 r14: 0x0000000000000001 r15: 0x0000000000000000 r16: 0x0000000000000000 r17: 0x0000000000000001 r18: 0x0000000000000000 r19: 0x0000000000000000 r20: 0x0000000000000000 r21: 0x0000000000000000 r22: 0x00000000005132e8 r23: 0x00000000005132e0 r24: 0x00000000005131d0 r25: 0x00000000005132e8 r26: 0x000000000138c164 r27: 0x00000000bfffea08 r28: 0x0000000000000002 r29: 0x0000000000000001 r30: 0x00000000006929b0 r31: 0x00000000012cc164 Binary Images Description: 0x1000 -

This is very likely a duplicate of bug 7274, which should be fixed in the latest nightly, r12854. *** This bug has been marked as a duplicate of 7274 ***

I tested it again with the new webkit (17th feb). The crash seems resolved: out of ~10 times there were no crashes. However the leaks keep occuring. They are reported to be: 1 WebBridge object, 1 JavaScript interpreter. Unfortunatly I do not get consistently: I get it only around 50% of the time, and I cannot determine what causes it and what doesn't. (If you want to replicate it, you may very well have to try several times: the "best" I got were 3 times in a row with no problems). I do not know if it may be important but Safari has reported the same leaks in other pages, and it was always those two leaks. However in those cases it is even harder to replicate it. Is there any way to help pin point what is causing this? For example is there any way to make safari only load some of the items in the page? Thank you

The best way to debug this is to download the source of the web page (you may want to use Firefox's save as 'Web Page, Complete'), and then verify that loading it locally still produces the leaks. Once you've done, that start removing "half" the content on the page and test again. If the top half doesn't have a leak, try loading the bottom half of the page. Hopefully one or the other should include the leak(s). Then continue to narrow the remaining content by cutting it in half each time. Eventually you will end up with a test case that reproduces the leak (which is VERY valuable!). Note that it's possible that you may only be able to reduce the content of the HTML page so far and still produce the link, so it may not be possible to reduce this to less than a dozen HTML tags, but that's okay. Any reduction may help identify the leaks. Also note that there may be a way to run Safari (or the Safari+WebKit nightlies) to report the *exact* location of the leak without the above work. I'm not sure how to do that off the top of my head; please check on IRC to find out if there's a way to do that. http://webkit.opendarwin.org/contact.html
