If we resurrect dying objects (non-marked, but not swept yet),

rb_fstring() used rb_gc_mark() to avoid freeing used string.
However, rb_gc_mark() set mark bit *and* pushes mark_stack.
rb_gc_resurrect() does only set mark bit if it is before sweeping.

RARRAY_RAWPTR(ary) returns (const VALUE *) type pointer and
usecase of this macro is not acquire raw pointer, but acquire
