NightlyCrashTriage/2018Q2

2018-04-20 - marcia

April 21 Nightly

No android build on 4/21
Attached a new signature to bug 1435343
Filed bug 1456150 Crash in static void alloc_system::platform::Template:Impl::oom. Perhaps someone can bucket it in the proper component.
bug 1455491 was filed on on 4-19 and now has 157 crashes in the top crashing signature
Ignored several single install crashes including mozilla::layers::OverscrollBehaviorInfo::FromStyleConstants

April 17 Nightly

bug 1433418 - Crash in SharedLibraryAtPath. This crash is a few months old, but it was an Android top crash on this Nightly. I commented and needinfo'd somebody.
bug 1455744 - Crash in java.lang.UnsatisfiedLinkError: Native method not found: android.media.AudioSystem.getOutputLatency:(I)I at android.media.AudioSystem.getOutputLatency(Native Method). Single install time, but this is the #2 Android crash, so I filed it.
bug 1455745 - Crash in mozilla::a11y::CreateHolderFromAccessible. Diagnostic assert, mostly from a single install time. But I see a comment saying these should be disabled, so I filed it just in case that is not expected.

4-16 Nightly

Filed bug 1454959 Crash in static js::jit::JitExecStatus EnterBaseline
Ignored several single installs including nsFrameConstructorState::~nsFrameConstructorState
Added another signature to Mac crash bug 1454094
Filed Fennec bug 1454966 Crash in <name omitted> | nsIFrame::IsVisibleConsideringAncestors. Goes back to when Nightly was in 60.

4-14 Nightly

Commented in bug 1443746 Crash in mozilla::CycleCollectedJSContext::PerformMicroTaskCheckPoint
Volume in bug 1453567 has increased. Pinged mystor on IRC for follow up.
Added another Mac signature to bug 1446900
Added another Mac signature to bug 1454094 Variable font sites are still crashing on Mac
Filed bug 1454430 Crash in static struct mozilla::layers::CompositorBridgeParent::LayerTreeState* mozilla::layers::GetStateForRoot, which goes back to 3-16

4-15 Nightly

bug 1454318 - not a crash in our code, but it's spiking so we might want to blacklist the affected driver
Not sure what to do about this Mac crash, it's not in our code but it seems to have started from build 20180413100443 so maybe it's our fault?
Quite a few single installation crashes across the three platforms

4-11 Nightly

Only one Nightly build per platform generated, oddly enough. Crash volume feels low, too. Back to 2 for 4/12.
Nothing else of interest that hadn't been filed already.

4-10 Nightly

bug 1453029 - Crash in JS::AutoSaveExceptionState::restore. A new (low volume) Windows crash I think in xpconnect
I filed a couple more issues, but none of them new for this build: bug 1453050, and bug 1453037, which looked to be from a build last week.

4-7/8 Nightly

Several Fennec crash signatures showed up in 4-7 build but have not been seen since then. Didn't bother filing a bug.
- cssparser::tokenizer::next_token::h2079e47df88c889d/
- cssparser::tokenizer::consume_name::hfc5357f1f9e128dd
- style::style_adjuster::StyleAdjuster::set_bits::hb61b6ab1258184bd
Added a signature and comment to bug 1446900
Filed bug 1452763 Crash in libobjc.A.dylib@0x9174

4-5 Nightly

bug 1442895 - Commented in bug. Top Android crash with something like 40% of all Android crashes. (Contrary to what njn wrote, there was one Nightly Android build.) Looks like a possible recurrence of the wcsrtombs crash.
Nothing much else. The display list megacrash was still going on, but seems to have gone away completely in later builds on this day.

Apr 06 Nightly

Not much going on. No Android builds, and none for Apr 05 either, though there is one for Apr 07.
Commented on some bugs.

04-04 Nightly

Filed: bug 1451891 - More crashes in __fixunsdfsi. A patch was landed for this crash signature, but the crash is still happening a lot, albeit a lot less often.
Filed: bug 1451913 - Crash in nsPIDOMWindowInner::UpdateWebSocketCount.
Commented: bug 1451467 - [Mac] Crash in <name omitted> | nsPresContext::ThemeChangedInternal. Top crash on OSX, by a lot.
bug 1451754 - Crash in MergeState::ProcessItemFromNewList. Commented in the bug. Hopefully this is simply a dupe of bug 1451384.
Filed and WONTFIXed: bug 1451897 - Crash in JS_YieldCooperativeContext. Probably a single user who enabled an unsupported pref.
Filed and WONTFIXed: bug 1451900 - Crash in mozilla::CooperativeThreadPool::RecheckBlockers. Another Quantum DOM pref user?
