    merge revision(s) 41325: [Backport #8554]
    
    * gc.c: Fixup around GC by MALLOC.
      Add allocate size to malloc_increase before GC
      for updating limit in after_gc_sweep.
      Reset malloc_increase into garbage_collect()
      for preventing GC again soon.
      this backport patch is written by nari.
