Created attachment 8346339 [details] stack GECKO_REFLOW_INTERRUPT_MODE=counter GECKO_REFLOW_INTERRUPT_FREQUENCY=1 GECKO_REFLOW_INTERRUPT_CHECKS_TO_SKIP=0 GECKO_REFLOW_MIN_NOINTERRUPT_DURATION=0 layout/generic/crashtests/381786-1.html ###!!! ASSERTION: Frame passed in not in reflow?: 'aFrame->GetStateBits() & NS_FRAME_IN_REFLOW', file /Users/jruderman/trees/mozilla-central/layout/base/nsPresShell.cpp, line 2725
Several other crashtests hit this assertion when I use the same env vars, but many of them don't hit it reliably. Am I doing something wrong that makes these tests less deterministic than they could be?
Created attachment 8350784 [details] [diff] [review] wallpaper Reflowing abs.pos. children of XUL frames currently happens after the delegating frame is fully reflowed (WillReflow/Reflow/DidReflow) so the IN_REFLOW bit is not set when nsAbsoluteContainingBlock checks for interrupts: http://mxr.mozilla.org/mozilla-central/source/layout/generic/nsAbsoluteContainingBlock.cpp#181 This sort of wallpapers the problem, but this stuff is pretty low priority so I don't think it's worth spending more time on. https://tbpl.mozilla.org/?tree=Try&rev=c7f5819c6206
