CefShutdown crashes when using external message loop

[Serhii]

I am integrating Chromium Embedded Browser into the existing windows application. I am using external hosting application and in OnTimer event I am running CefDoMessageLoopWork(). Actually all browsers are loaded appropriately. But application crashes aiming to run CefShutdown(). I am closing browsers with call _browser->GetHost()->CloseBrowser(true);

What can be possible reasons of CefShutdown failing?

You need to wait for OnBeforeClose callbacks from all browsers and then call CefDoMessageLoopWork a few more times to empty the message queue before calling CefShutdown. See also the many related threads on this forum.
