--- Comment #9 from Jakub Jelinek <jakub at gcc dot gnu.org> --- (In reply to Jakub Jelinek from comment #8) > The problem is that TYPE_FIELDS in C++ don't contain just FIELD_DECLs, but > lots of other stuff, e.g. TYPE_DECLs, CONST_DECLs, FUNCTION_DECLs. Forgot about VAR_DECLs in this list (i.e. static data members).
