Hi, can you check what is up with this rust panic in servo/components/style/rule_tree/mod.rs , please? First time I see it. Be aware that it is in the range when bug 1400438 had landed - it got backed out after that.

So we're dropping a rule node which still has a first-child pointer? That's really scary.
The drop in frame 12/13 is http://doc.servo.org/geckolib/style/style_resolver/struct.ResolvedStyle.html This makes me suspect the rule node caching stuff might be what caused this, since ComputedValues has a StrongRuleNode in it. Unsure if that actually touched unsafe code.

So this is 32 bit only. It's possible that bug 1391341 regressed this by breaking the layout tests (which I thought we run now, but it seems like we don't). I had manually done 32 bit tests when working on that patch but the patch did change later, so it's worth checking again.

Unsure if that actually > touched unsafe code. You're talking about the reset struct caching? The approach we landed didn't touch the rule tree at all. NI to keep investigating until we know whether this blocks.

The bug is NOT a struct layout issue. We do have layout failures on 32 bit however (on structs which IIRC we don't read/write from), and our Servo_* functions are mismatching by a few const annotations. ---- bindings::root::mozilla::bindgen_test_layout_SchedulerGroup stdout ---- thread 'bindings::root::mozilla::bindgen_test_layout_SchedulerGroup' panicked at 'assertion failed: `(left == right)` left: `88`, right: `84`: Size of: SchedulerGroup', /home/manishearth/mozilla/servo/target/i686-unknown-linux-gnu/debug/build/style-41867086c3ec5c50/out/gecko/structs_debug.rs:6531:12 note: Run with `RUST_BACKTRACE=1` for a backtrace. ---- bindings::root::mozilla::css::bindgen_test_layout_ImageValue stdout ---- thread 'bindings::root::mozilla::css::bindgen_test_layout_ImageValue' panicked at 'assertion failed: `(left == right)` left: `80`, right: `76`: Size of: ImageValue', /home/manishearth/mozilla/servo/target/i686-unknown-linux-gnu/debug/build/style-41867086c3ec5c50/out/gecko/structs_debug.rs:1853:16 failures: bindings::root::mozilla::bindgen_test_layout_SchedulerGroup bindings::root::mozilla::css::bindgen_test_layout_ImageValue
ni emilio on the layout issue though, seems to be a bindgen bug which we should investigate once all this settles down

The struct layout issues are both https://github.com/rust-lang-nursery/rust-bindgen/issues/380

investigated this for a day and a half, both I and emilio couldn't find anything weird. Nor were we able to repro this crash. Not sure what to do now.

Alright, given that this is a single instance, I'm resolving WFM.

fwiw, bughunter hit this on windows 7 32bit at <https://my.yahoo.com/>. I re-tested the url but was not able to reproduce again either on windows 7 or windows 10. I presume this is due to an ad which will make it problematic to get a reproducible url.
