            Bug ID: 287553
           Summary: [GLib] TestUIClient.cpp dereferences std::optional
                    without a contained value
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Tools / Tests

There are a few instances where Tools/TestWebKitAPI/Tests/WebKitGLib/TestUIClient.cpp uses "*foo = value" instead of "foo = value" to set a value into a std::optional. This is using "operator*" which returns a reference to the contained value, and then assigning to it. Dereferencing a std::optional without a contained value is undefined behaviour, and triggers C++ library assertions (see bug #266396).
