Al analysed this some time ago. When we say something is const then _sometimes_ gcc annotate the section as const(*) - sometimes not. So if we have two variables/functions annotated __*const and gcc decides to annotate the section const only in one case we get a section type conflict. (*) it is named something else I do not recall at the moment in linker language.
