           Summary: Web Inspector: build: InspectorJSTypeBuilders.h breaks
                    strict-aliasing rules
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: prlw1 at cam.ac.uk


./DerivedSources/JavaScriptCore/InspectorJSTypeBuilders.h:116:66: warning: deref
erencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing
]
             return *reinterpret_cast<RefPtr<Location>*>(&m_result);


It looks as though that header is careful about trying to only cast compatible objects.

Need some unions or a sprinkling of -fno-strict-aliasing ?

This is using the recent webkitgtk-2.3.91 tarball.
