            Bug ID: 252449
           Summary: [GCC] Ubuntu 20.04 build error after 260367 at main
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: New Bugs
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: dpino at igalia.com

The WebKitGTK Ubuntu 20.04 build bot is failing with the following error:

```
error: could not convert ‘context.WebCore::WebGLExtensionScopedContext::operator->()->WebCore::WebGLRenderingContextBase::graphicsContextGL()->WebCore::GraphicsContextGL::getQueryObjectui64EXT((& query)->WebCore::WebGLTimerQueryEXT::<anonymous>.WebCore::WebGLContextObject::<anonymous>.WebCore::WebGLObject::object(), pname)’ from ‘GCGLuint64’ {aka ‘long unsigned int’} to ‘WebCore::WebGLAny’ {aka ‘std::variant<std::nullptr_t, bool, int, unsigned int, long long int, long long unsigned int, float, WTF::String, WTF::Vector<bool, 0, WTF::CrashOnOverflow, 16, WTF::FastMalloc>, WTF::Vector<int, 0, WTF::CrashOnOverflow, 16, WTF::FastMalloc>
```

This bug is similar to https://bugs.webkit.org/show_bug.cgi?id=244568. In this case, since WebGLAny doesn't support "long unsigned" it's necessary to do an explicit static cast to "long long unsigned" (supported by WebGLAny).
