Cef OSR crashed on Debug mode.

[Arion]

I have built a Cef OSR program using CefClient code.

But now it will crash if I run it on Debug mode.

Code: Select all

[0827/155402.586:FATAL:simple_watcher.cc(134)] Check failed: task_runner_->RunsTasksInCurrentSequence().[/color]

There are my main render loop and cef call.

Code: Select all

   while (!m_exit)
   {
      gTimer.Tick();
      float dt = gTimer.DeltaTime();

      cef_app->RenderCef(dt);

      char f_str[10];
      sprintf(f_str, "%f", dt);
      SDL_SetWindowTitle(m_mainWindow, f_str);

      gApp->update(dt);

      PollEvent(event);

      cef_app->LoopWork();
   }

   cef_app->Shutdown();

   gApp->shutdown();


the LoopWork() function is the wrapper for CefDoMessageLoopWork().

I don't know why it crashed, but when I run it on Release mode it is run well, no warning, no error.

What OS and CEF version? What is the full symbolized call stack for the crash?

Hi,

Any solution to this problem? since I am seeing the same.
Please reply if anyone knows.

[linuxcef9]

I ran into same issue and did some analysis.
Are you on a domain joined machine by any chance? If yes, go to your proxy settings (inetcpl.cpl ->Connections->Lan Settings) or via chrome://settings and search for proxy and uncheck 'automatically detect settings' . Let me know if that works.
