CEF Crash in MessagePumpForUI::ScheduleNativeTimer

[zhangwenlong]

I have a crash in MessagePumpForUI::ScheduleNativeTimer (86 version)
In ScheduleNativeTimer, I see it check the value in_native_loop_ failed.
the dump:
libcef.dll!logging::LogMessage::~LogMessage()
libcef.dll!logging::LogMessage::~LogMessage()
> libcef.dll!base::MessagePumpForUI::ScheduleNativeTimer(base::MessagePump::Delegate::NextWorkInfo next_work_info)
libcef.dll!base::MessagePumpForUI::HandleWorkMessage()
libcef.dll!base::MessagePumpForUI::MessageCallback(unsigned int message, unsigned __int64 wparam, __int64 lparam, __int64 * result)
libcef.dll!base::RepeatingCallback<bool (unsigned int, unsigned long long, long long, long long *)>::Run(unsigned int args, unsigned __int64 args, __int64 args, __int64 * args)
libcef.dll!base::win::MessageWindow::WindowProc(HWND__ * hwnd, unsigned int message, unsigned __int64 wparam, __int64 lparam)
libcef.dll!base::win::WrappedWindowProc<&base::win::MessageWindow::WindowProc>(HWND__ * hwnd, unsigned int message, unsigned __int64 wparam, __int64 lparam)
I use a timer call the CefDoMessageLoopWork function every 10 ms.
Does anyone know why？
Thank you

What OS? Does the crash reproduce with “cefclient.exe --external-message-pump”?

[zhangwenlong]

windows（86 debug version）
the cefclient.exe is no such problem.
I think I know why.
I drag a view component in html，it produced a window message to system, it crash.
I can disable dragging, But I didn't understand the principle.
