Do you mean that parser_obstack is effectively a per-toplevel-decl object and that it is supposed to be dead at the end of the object's parsing, although in the present case there are objects associated with different toplevel decls allocated on it that point to each other? And I presume label_context_stack_vm is not explicitly reset to NULL on function exit because of nested functions? Maybe a few sanity checks can be added to c_parser_translation_unit so as make implicit assumptions like these more explicit. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21879
