           Summary: Possible Error in Cairo Image renderer
           Product: WebKit
           Version: 420+ (nightly)
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: WebKit Misc.
        AssignedTo: webkit-unassigned at opendarwin.org
        ReportedBy: jhaygood at spsu.edu


I'm currently working on an initial GTK+ 2 port, and while implementing the
image stuff (to see if indeed the Cairo implementation works on GTK+ 2.8), GCC
4.1 noticed a possible error in either the header for ImageDecoder.h or the
consumer in ImageSourceCairo.cpp:

Header has this:

virtual RGBA32Buffer frameBufferAtIndex(size_t index) = 0;

Source has this:

RGBA32Buffer& buffer = m_decoder->frameBufferAtIndex(index);

Does frameBufferAtIndex really return a reference or the actual object? It
appears to be accessing like the regular object...
