The + recursion marking of CRuby needs checking stack overflow and the + fail-safe system, but these systems not good at partial points, + for example, marking deep tree structures. [ruby-dev:46184] + [Feature #7095] + + * configure.in (GC_MARK_STACKFRAME_WORD): removed. It's used by + checking stack overflow of marking. + + * win32/Makefile.sub (GC_MARK_STACKFRAME_WORD): ditto. + + * gc.c (free_stack_chunks): it is used only when per-VM object space + is enabled. + + * gc.c (rb_objspace_call_finalizer): mark self-referencing finalizers + before run finalizers, to fix SEGV from btest on 32bit. + + * gc.c (gc_mark_stacked_objects): extract from gc_marks(). + + * gc.c (rb_objspace_call_finalizer): call gc_mark_stacked_objects + at suitable point. + + * gc.c (init_heap): call init_mark_stack before to allocate + altstack. This change avoid the stack overflow at the signal + handler on 32bit, but I don't understand reason...
