Reproducible: Always

An inline (gray background) relative element contains an absolutely positioned one (red background.) If the browser window is slowly resized so that the inline element starts at the end of a line, there is usually a crash (in Windows XP.) Addition of some white-space seems to fix the problem.

Here's the crash report I got for this: bp-de7e95de-b662-11dc-aee5-001a4bd43e5c The first 14 frames look the same as Bug 398332. duplicate?

Let's make it dependent on that bug and see whether the possible patch in that bug fixes this crash.

Does not crash for me on RC1 Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9) Gecko/2008051206 Firefox/3.0 and also: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9pre) Gecko/2008052816 Minefield/3.0pre and Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9pre) Gecko/2008052817 Firefox/3.0pre (Debug Builds with the Patch from Bug 398332 included) and the testcase. Bruno, do you still see the crash on the Firefox 3RC1 Build ?

The testcase no longer crashes with the latest build after today's checkin for bug 398332. Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9pre) Gecko/2008052810 Minefield/3.0pre ID:2008052810

On OS X 10.5.2 The test case crashes with Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9pre) Gecko/2008052704 Minefield/3.0pre But the latest hourly from tinderbox no longer crashes (after the checking for bug 398332): Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9pre) Gecko/2008052816 Minefield/3.0pre

Yes, it does not crash anymore with the nightly builds that I get now, both on XP: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9pre) Gecko/2008052901 Minefield/3.0pre and on OS X: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9pre) Gecko/2008052904 Minefield/3.0pre I believe this can be changed to FIXED.

Could people here create a simple page which crashes when it's loaded in one of the buggy builds but doesn't when loaded in one of the latest, non-crashy builds? Good for making sure this never starts crashing again.
