Crash Data

This bug was filed from the Socorro interface and is report bp-88642585-0116-4d21-8c6d-b3e070180831. ============================================================= This is topcrash #13 for the Windows nightly 20180830111745 with 6 crashes in two different installations -- so it's obscure, but I think is real. Top 10 frames of crashing thread: 0 xul.dll mozilla::layout::PRenderFrameChild::SendNotifyCompositorTransaction ipc/ipdl/PRenderFrameChild.cpp:43 1 xul.dll mozilla::dom::TabChild::NotifyPainted dom/ipc/TabChild.cpp:2947 2 xul.dll nsresult mozilla::widget::PuppetWidget::Paint widget/PuppetWidget.cpp:1083 3 xul.dll mozilla::widget::PuppetWidget::PaintTask::Run widget/PuppetWidget.cpp:1123 4 xul.dll mozilla::SchedulerGroup::Runnable::Run xpcom/threads/SchedulerGroup.cpp:337 5 xul.dll nsThread::ProcessNextEvent xpcom/threads/nsThread.cpp:1167 6 xul.dll NS_ProcessNextEvent xpcom/threads/nsThreadUtils.cpp:519 7 xul.dll mozilla::ipc::MessagePump::Run ipc/glue/MessagePump.cpp:97 8 xul.dll MessageLoop::RunHandler ipc/chromium/src/base/message_loop.cc:318 9 xul.dll MessageLoop::Run ipc/chromium/src/base/message_loop.cc:298 =============================================================

This looks like a bunch of null derefs. I see 66 of these crashes on release, too, but 26 in Nightly, so that does look like a big increase. Matt, do you have any ideas what might be going on here? This code was changed somewhat recently as part of WebReplay, but if WebReplay is enabled the code wouldn't run, and it shouldn't do anything different if it is disabled.

This probably doesn't belong in the IPC component; it looks like either Widget or maybe DOM :: Content Processes.

Component: IPC → Widget
Whiteboard: qa-not-actionable
Flags: needinfo?(matt.woodrow)

The crashes in the last 6 months with this signature are all on version 60, so I think we can close this.
