            Bug ID: 274255
           Summary: [WPE][GTK] Enable fatal criticals in WebKit
                    subprocesses
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKitGTK
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: mcatanzaro at redhat.com

Critical warnings should only be used to indicate programmer error. By default, they are "soft assertions" that allow program execution to continue even though we know the process is no longer operating correctly because a bug has occurred. This is a bad default. Let's crash instead, to make it easier to debug the problem, encourage bug reports, and downgrade any code execution issues into denial of service.

This will significantly increase crashes in our multimedia code. I think the rest of WebKit is more or less in good state, but there will certainly be more crashes here and there. I'm confident it will be worth it!

We cannot do this in the UI process because that decision should be left up to the application. Only do this for subprocesses.
