In build_filter(), val is only initialized if filter->rval->type is either EXPR_NUMBER or EXPR_STRING. AS far as I can understand that is expected at that point. Howvever, it doesn't cost much to initialize it in case the parser let some bogus request pass by and it should prevent the static analyser to complain.
