Hang using latest nightly
User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:10.0a1) Gecko/20111004 Firefox/10.0a1 Build ID: 20111004030858 Steps to reproduce: 1) Open http://forum.shrimprefuge.be/showpost.php?p=833327&postcount=1342 in a tab. 2) Click 'Toon' button. 3) Click 'Verklein' button, close the tab or close Firefox. Actual results: Firefox will hang and soak up a CPU core completely every single time. Expected results: The page should return to the state it was in before clicking the 'Toon' button. The hang occurs with the latest nightly, but not with the latest Aurora build. Managed to trigger the hang consistently on: -Windows 7 64bit using both 32 and 64bit nightlies -Windows XP -Ubuntu 10.10 32bit running in VirtualBox
confirming with Mozilla/5.0 (Windows NT 6.1; rv:10.0a1) Gecko/20111003 Firefox/10.0a1 SeaMonkey/2.7a1 This works with FF7.0.1 Will try to find a regression range and or stack trace later

My money is on Ehsan here....
Looks like a RecreateFramesForContent leading to lots of CaptureFrameState..... Are we just recreating over and over or something else?
This was a stupid mistake that I made. nsTableOuterFrame::GetChildLists was returning the principal child list twice.

This patch https://hg.mozilla.org/mozilla-central/rev/306153bf7a41 was effectively wallpapering over this bug... :-) So I backed it out now that this is fixed for real: https://hg.mozilla.org/integration/mozilla-inbound/rev/a9c247a14c62

Now that we have a better understanding of this bug, is it of enough concern (and the patch low enough risk) to consider for Beta 10?
