Stability Report [Weekly]

• Trunk crashes needing an owner or attention:
  • bug 827946 - skia::BGRAConvolve2D
  • bug 828034 - mozilla::ipc::RPCChannel::EnteredCxxStack
  • bug 830654 - js::ObjectImpl::getPrivate
  • bug 829909 - nsWindow::Enable @ UserCallWinProcCheckWow (was assigned to aklotz by release management, needs attention)
• bug 806820 - probably Facebook-triggered, connected to iterators in JS
  • If anyone has been seeing this, we'd be very happy to find steps to reproduce so it can be debugged.
• bug 822438 - js::Interpret or js::mjit::JaegerShot on wiadomosci.onet.pl
  • Haven't heard back on our Polish contact trying to get a sample of the code that was pushed and then pulled back on that site.
  • If anyone has contacts to that site or can help us to get in contact with their team to receive a sample of that code which was triggering our crashes, that would be very helpful. We know it's a bug on our side that they triggered, we need to try and reproduce as the stacks aren't too helpful, though (unless someone can get a clue by looking into minidumps).
