I notice also that in test_inspect there is the following:
FOR_EACH_PTR_NOTAG(filelist, file) {
struct symbol_list *syms = sparse(file);
expand_symbols(syms);
concat_symbol_list(syms, &view_syms);
} END_FOR_EACH_PTR_NOTAG(file);
Therefore if the symbols are dropped when the file scope ends, what is
supposed to happen above?
Thanks and Regards
