Comment 4 2010-05-13 20:15:27 PDT
I created a Hotmail account, and using the nightly mentioned by the originator (r59204) I habe able to reproduce this problem a few times. Just hammering back / forward and jumping between the Inbox and New message screens. I haven't been able to get concrete steps, so maybe this is based on advertisements. It took a lot longer, but I finally hit an ASSERT in a debug build: ASSERTION FAILED: item->documentSequenceNumber() == history()->currentItem()->documentSequenceNumber() (/Users/pecoraro/Code/webkit-open-source/WebCore/loader/FrameLoader.cpp:3647 void WebCore::FrameLoader::navigateWithinDocument(WebCore::HistoryItem*)) Program received signal EXC_BAD_ACCESS, Could not access memory.

After commenting out (but logging) when I hit the above ASSERT it looks like that doesn't cause a crash. Doing some more "stress testing" of back & forward I hit the following ASSERT. The other assert didn't appear to have been hit. ASSERTION FAILED: !cachedPage || cachedPage->document() == m_frame->document() (/Users/pecoraro/Code/webkit-open-source/WebCore/loader/HistoryController.cpp:197 void WebCore::HistoryController::invalidateCurrentItemCachedPage()) Program received signal EXC_BAD_ACCESS, Could not access memory.

FWIW, I never saw any of these history controller assertions. If you can find exact steps to reproduce this, please file a new bug, as it's clearly a different issue.

Comment 7 2010-05-13 22:05:20 PDT
I can only reproduce this with the r59204 nightly. Normally after just a few tries. My steps are. 1. Navigate to hotmail.com 2. Log in. 3. Click "New" for a new email. 4. Click "Inbox" 5. Furiously go back and forth a few times. 6. If that fails Go between "Inbox" and the "Manage Folders" link. I haven't been able to reproduce this on ToT (debug). I just finished a release build.

Comment 9 2010-05-13 22:19:45 PDT
Weird that I can't get this to reproduce in the nightlies. I've commented out both of the asserts I've hit (in hopes it would lead to the crash) and I put logging there instead. I've managed to reproduce both of those but not produce a crash. I'm calling it a night.

Created attachment 56056 [details] reduced test case (will crash) Attaching a reduced test case. As mentioned before, the actual fix is trivial, will wrap it up in the morning.

Comment 11 2010-05-14 10:13:42 PDT
Created attachment 56083 [details] proposed fix I removed the helper class, because: 1) I didn't like its name. 2) In a tricky place like this, it's probably best to be explicit about which tokenizer is being accessed. Technically, it would be just as easy to have the checks in helper class by making it hold a Document pointer.
