preprocessed DerivedSources/WebCore/WebCoreJSBuiltinInternals.cpp:
-------------------------------------------------------------------
....
    JSDOMGlobalObject::GlobalPropertyInfo staticGlobals[] = {
    };
    globalObject.addStaticGlobals(staticGlobals, sizeof(::WTF::ArrayLengthHelperFunction(staticGlobals)));
....

It seems the new script doesn't handle empty staticGlobals[] properly.
I don't know anything about this code path and don't plan to fix it
myself, I just reported to let you know this build break.
