This is an assertion failure. Here's the assertion quoted from the log (also present in comment 0 but hard to see due to how to Bugzilla truncates long code-blocks):

MOZ_ASSERT(!aPrevFrame || (!aPrevFrame->GetNextContinuation() || (aPrevFrame->GetNextContinuation()->HasAnyStateBits( NS_FRAME_IS_OVERFLOW_CONTAINER) && !aPrevFrame->HasAnyStateBits(NS_FRAME_IS_OVERFLOW_CONTAINER)))) (aPrevFrame must be the last continuation in its chain!) [@ nsFrameManager::InsertFrames] | layout/base/crashtests/1489149.html

Here's where that assertion lives:
https://searchfox.org/firefox-main/rev/33bba5cfe4a89dda0ee07fa9fbac578353713fd3/layout/base/nsFrameManager.cpp#74-84

Here's the test that's triggering this issue:
https://searchfox.org/firefox-main/rev/33bba5cfe4a89dda0ee07fa9fbac578353713fd3/layout/base/crashtests/1489149.html

It looks like we also have bug 1714701 filed with a fuzzer testcase that triggers this assertion.

Depends on: 1714701

Comment 0 (and the other starred intermittent-failures so far) is from Android, but we're getting this issue (Crashtest 1489149.html triggering this assertion-failure) on Linux as well -- TreeHerder is just suggesting bug 1645714 as the bug for the Linux reports for some reason.

The reports on LInux so far are:

Hmm, both of the linux test-failures are from the same push that included bug 2008148's commit. I'm suspicious that this is a regression from that bug.

(The assertion being able-to-fail is a preexisting problem per bug 1645714 and bug 1714701; but it's new that this particular crashtest now intermittently triggers it, and that seems to be correlated with bug 2008148.)

Keywords: regression

Regressed by: 2008148

Bug 1645714 comment 2 suggests that, at least in the case that TYLin was looking into there, the assertion was incorrect & harmless.

Unless anyone has cycles to dive deeply in... maybe for now it'd be worth morphing this fatal-assertion into a nonfatal-assertion, and then we can give 1489149.html an asserts(0-1) annotation...

emilio: since you were just looking at this area of code in bug 2008148 and might have some of the invariants & bits of deduplicated logic paged into your head... do you agree that downgrading the assertion makes sense here?

Attached file Bug 2008711 - When processing float insertions, compare placeholders rather than out of flow tree position. r=dholbert,layout-reviewers — Details

It is true that the CompareTreePosition call goes through placeholders,
but it's not guaranteed to do so if the two frames are already children
of the CB.

Make the crashtest crash reliably without my patch by sprinkling some
getBoundingClientRect() around.
