            Bug ID: 224209
           Summary: [WPE][GTK] Null pointer dereference when child process
                    exits immediately
           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 gnome.org
                CC: bugs-noreply at webkitgtk.org

In https://github.com/flathub/org.gnome.Epiphany/issues/21 we discovered that when the child process exits immediately after it is spawned, g_subprocess_get_identifier() will return nullptr. In this case, we should crash cleanly with SIGABRT via g_error(), rather than crashing with a null pointer dereference inside g_ascii_strtoll(). SIGABRT is much nicer than SIGSEGV and indicates that we really do want to crash here, whereas SIGSEGV is just a bug.
