           Summary: LayoutUnit overflows in
                    fast/events/constructors/(mouse|wheel)-event-construct
                    or.html
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Keywords: Gtk, LayoutTestFailure
          Severity: Normal
          Priority: P2
         Component: WebKit Gtk
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: zandobersek at gmail.com


The following two tests are outputting out-of-bounds messages in LayoutUnit:
fast/events/constructors/mouse-event-constructor.html
fast/events/constructors/wheel-event-constructor.html

The message:
ERROR: !(isInBounds(value))
../../Source/WebCore/platform/LayoutUnit.h(325) : void WebCore::LayoutUnit::setValue(int)
ERROR: !(isInBounds(value))
../../Source/WebCore/platform/LayoutUnit.h(325) : void WebCore::LayoutUnit::setValue(int)

This is happening when testing the bounds of WebIDL's long type for clientX and clientY attributes. The tests fail, as the diffs show:
