OnProtocolExecution allow_os_execution does not work

[naoki5]

Hello,

My application uses CefResourceRequestHandler::OnProtocolExecution.
I have specified true for the argument "allow_os_execution".
My application handles mailto links and "zoom" invitation URLs correctly.
However, it does not work with CEF 87.
It worked fine up to CEF 86.

Also, I'm calling CefBrowser::StopLoad to prevent the view from opening a blank page, but CEF 87 raises an exception.

Is there a way to get it to work as it did before CEF86?

What is the symbolized call stack for the exception?

This is when I used CEF built with "proprietary_codecs = true".
This is the call stack when I click the "mailto" link and get an exception.

[magreenblatt]

Looks like https://bitbucket.org/chromiumembedded/cef/issues/3052

Looks like https://bitbucket.org/chromiumembedded/cef/issues/3052

Thank you.
I wait for the fix to take effect.

Is it another problem that "allow_os_execution" doesn't work?
What should I do about this matter?

[magreenblatt]

Please add a bug for the allow_os_execution problem if it still reproduces after the crash fix.

[naoki5]

I have built CEF 87.1.11.
CefBrowser::StopLoad does not raise an exception.
Also, "allow_os_execution" is working.
Thank you.
