Answer 3

After spending a few hours trying to figure out the same error message this morning (along with a bunch of nondescript nullpointerexceptions from Eclipse) I compared the Eclipse project files with previous version and found that Eclipse had added an extra node to my .cproject file, making it three in total. I removed this one, which was the one added by Eclipse and also the last one in the file.

    <cconfiguration id="0.1230402123.1377291156">
        <storageModule buildSystemId="org.eclipse.cdt.managedbuilder.core.configurationDataProvider" id="0.1230402123.1377291156" moduleId="org.eclipse.cdt.core.settings" name="Debug">
            <externalSettings/>
            <extensions>
                <extension id="org.eclipse.cdt.core.VCErrorParser" point="org.eclipse.cdt.core.ErrorParser"/>
                <extension id="org.eclipse.cdt.core.GmakeErrorParser" point="org.eclipse.cdt.core.ErrorParser"/>
                <extension id="org.eclipse.cdt.core.CWDLocator" point="org.eclipse.cdt.core.ErrorParser"/>
                <extension id="org.eclipse.cdt.core.GCCErrorParser" point="org.eclipse.cdt.core.ErrorParser"/>
                <extension id="org.eclipse.cdt.core.GASErrorParser" point="org.eclipse.cdt.core.ErrorParser"/>
                <extension id="org.eclipse.cdt.core.GLDErrorParser" point="org.eclipse.cdt.core.ErrorParser"/>
            </extensions>
        </storageModule>
        <storageModule moduleId="org.eclipse.cdt.core.externalSettings"/>
    </cconfiguration>

After removing that and restarting Eclipse everything was working again.

I hope this helps someone. I'm not sure whether this was unique or something that causes issues for others, but clearly the error points towards a CDT problem and therefore comparing the .cproject file to previous versions (or default ones) for changes is worth a shot.
