Crashed thread when adding second browser to cefclient

[chortle]

CEF Version: cef_binary_3.2272.2077_macosx64

Actions taken:
1. Downloaded 2272 code and ran cmake for mac64 bit
2. Tried to create a new browser within the main window content view:

// Modified the size of the default browser loaded with the code
window_info.SetAsChild(contentView, 5, 310, kWindowWidth, kWindowHeight-200);

// Create new browser view.
CefWindowInfo window_info2;
CefBrowserSettings settings2;
window_info2.SetAsChild(contentView, 5, 5, kWindowWidth, kWindowHeight - 300);
CefBrowserHost::CreateBrowser(window_info2, g_handler.get(),
"http://www.youtube.com", settings, NULL);

3. Compiled, ran it and started clicking around. Got the following error. Please advise on what I may be doing wrong. I am new to CEF and hoping that the fix is simple and something silly that I might have done.

It looks like you were exiting the application when the crash occurred. You likely need to modify ClientHandler so that it only exits the application after OnBeforeClose has been called for both browser windows.
