These signatures are showing up in recent Nightly top crashes, the modules in question seem to be from the recent Windows 10 (10.0.14393.1066) and Windows 7 (6.1.7601.23714) updates. The symbols are currently being served up by symbols.mozilla.org just fine: http://symbols.mozilla.org/kernelbase.pdb/95A44B9D541E4EB393DAC0B2858461321/kernelbase.sym http://symbols.mozilla.org/ntdll.pdb/CDB4B8AE7E824BB1A96CF1BEEC2859CD2/ntdll.sym Maybe these crashes just need to be reprocessed?
I have reprocessed 71652e69-d919-4e3b-b465-f65d50170419 which had `kernelbase.dll@0x4796e` as a signature, and now has `mozilla::ipc::MessageChannel::WaitForSyncNotify | mozilla::ipc::MessageChannel::Send | mozilla::plugins::PPluginInstanceChild::SendShowDirectDXGISurface`. I assume reprocessing for those three signatures will solve this problem. Starting that now.
All crashes containing any of those signatures since the beginning of this year have been sent for reprocessing. It should be a matter of minutes before they all have correct signatures.
