The reason for this seems to be the implementation of CSS page breaking. This does not occur if there is only one page of information. Reproducible: Always Steps to Reproduce: 1. View file (http://www.tensen.net/research/firefox/display.html) 2. Print Preview Actual Results: Firefox crashes and brings up the crash manager. Expected Results: A preview of the document should have been generated styling the page with the CSS linked to with media=print according to the latest CSS standard published by the W3C. This problem occured on Microsoft Windows 2000 5.00.2195 Service Pack 4

This bug seems to apply only to the 'float' directive. This bug could lead to a loss of data in a different context (fill in a form on an affected page without submitting, print preview, crash, loss of data).

If firefox crashed and brought up the crash manager (called Talkback) did you submit crash data to mozilla? If so, what TalkbackID was it? (You can find talkback.exe in your firefox installation dir, run it, and it will list the crashes you have submitted).

These are two talkback ids associated with this problem. TB21774577X TB21774578Q

This happens on Linux branch and trunk, too.

Testcase from url, simplified a bit more, this crashes on print preview for me on current trunk build.

testcase created at 2006-08-04 12:34 PDT does not crash Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.7.8) Gecko/20050524 Fedora/1.0.4-4 Firefox/1.0.4 but url does.

Sorry, indeed, the testcase is also only crashing in landscape format for me. It crashes also Mozilla1.7.12, so no (recent) regression.

It may be moot at this point since this bug seems to be platform independent, but the url also crashes Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8.0.6) Gecko/20060728 Firefox/1.5.0.6

Martijn the stack is a typical cellmap crash watch for the rowgroups and how they split if you like to work on it, I am away till 06-08-21

Comment on attachment 235667 [details] [diff] [review] patch have a look at OrderRowGroups to understand why reordering does not help with this.

(In reply to comment #8) > Sorry, indeed, the testcase is also only crashing in landscape format for me. > It crashes also Mozilla1.7.12, so no (recent) regression. Don't we need a separate bug split off for this testcase using landscape? I too no longer crash in portrait mode with the attachment, and neither landscape nor portrait with the live URL in comment 0, but I *do* still crash with Martijn's testcase in comment 8, with landscape.

(In reply to comment #14) > I too no longer crash in portrait mode with the attachment, and neither > landscape nor portrait with the live URL in comment 0, but I *do* still crash > with Martijn's testcase in comment 8, with landscape. Yeah, I'm crashing too with a 2006-09-07 trunk build, talkback ID: TB23149944K This is still with the same kind of backtrace -> reopening

argh, I forgot the other half to get reviewed. The problem is that we need something like http://bonsai.mozilla.org/cvsblame.cgi?file=mozilla/layout/tables/nsTableRowGroupFrame.cpp&rev=3.367&mark=1528-1531#1525 at the end of the ::reflow method instead of the incr. reflow methods. If we do this the testcase, will trigger the float hang like bug 285608.

Robert, I think this is the right thing to do, however once checked in the testcase will not crash but hang due to bug bug 285608. I am not sure that this is an improvement (other that we access deleted memory)

We have this already on reflow branch http://bonsai.mozilla.org/cvsblame.cgi?file=mozilla/layout/tables/nsTableRowGroupFrame.cpp&rev=REFLOW_20060830_BRANCH&root=/cvsroot&mark=1245-1250#1240

fix checked in. Please note that the new behavior on the test case could/should be a hang

Verified FIXED with the testcase at https://bugzilla.mozilla.org/attachment.cgi?id=232185 (no longer causes a crash, but hangs due to bug 285608) using build 2006-10-01-08 of SeaMonkey trunk under Windows XP.

fix checked in into branch

Tried to verify on XP by checking to see if Firefox 2.0.0.14 (also 2.0.0.13) crashed with original test case, but it didn't. So I tried the test case mentioned in comment #8. Print preview in landscape mode crashed it. Then I looked at Firefox 2.0.0.15pre, but while it doesn't crash, it hangs, becomes unresponsive and eventually you get the option to kill it.
