Steps to reproduce: Open http://people.mozilla.com/~bstover/testcase.scrolling.html or a post in http://www.google.com/reader/i/ that overflows the viewport width. Scroll the overflow content. Results: The content process hangs (the page stops painting; loading new remote pages has no effect; tabs won't close). Mark Finkle reports that the content process crashes in his build. I can reproduce this 100% in a local trunk opt build on Galaxy Tab, but not in desktop Linux. I cannot reproduce it in the 2011-04-29 nightly build. Regression range: http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=ff152a406ed3&tochange=a008a3fda2b5 Bug 640048 is the most obviously related changeset in that range, but it could be something else.
I can verify that bug 640048 is the cause. I could 100% reproduce the crash on http://people.mozilla.com/~bstover/testcase.scrolling.html With the patch backed out, I could not reproduce the crash at all. I backed out the patch: http://hg.mozilla.org/mozilla-central/rev/44f2b2c318b0
