Created attachment 262466 [details] testcase (hangs Firefox when loaded) This testcase makes Firefox (Mac trunk debug) hang, spewing the following assertion the whole time: ###!!! ASSERTION: Bogus availSize.width; should be bigger: '!mContentFrame || GetContentMinWidth(aReflowState.rendContext) <= availSize.width', file /Users/jruderman/trunk/mozilla/layout/forms/nsFieldSetFrame.cpp, line 474
I have no idea what the deal is with the width, offhand, but the hang is due to height growth. nsStackLayout keeps looping while the kid is growing, and each time it sets a computed height on the fieldset, the fieldset reflows at that height, overflows (because the content frame is height: 100% and the legend takes some space), nsFrame::BoxReflow does: aDesiredSize.height = aDesiredSize.mOverflowArea.YMost(); which increases aDesiredSize.height from what it used to be (which was equal to the computed height). So we do this over and over again forever.
Still hangs on trunk.
The testcase has become worksforme between 2007-11-05 and 2007-11-06: http://bonsai.mozilla.org/cvsquery.cgi?treeid=default&module=all&branch=HEAD&branchtype=match&dir=&file=&filetype=match&who=&whotype=match&sortby=Date&hours=2&date=explicit&mindate=2007-11-05+03&maxdate=2007-11-06+09&cvsroot=%2Fcvsroot
Is there a reason to not close it?
I haven't tested it on mac and I know that Jesse normally reacts quite quickly to comments (and maybe someone is interested in what fixed it).
Works for me on Mac trunk debug.
Works for me, too. No crash, no assertion failures.
