Description

taruiさんが入れてくださった r41325 のバックポートをお願いします。

LazySweep中にmalloc_increaseがクリアされておらず、LazySweep中にmallocが発生すると期待していないタイミングでGCが動いてしまっていました（GCの二度打ち）。
パッチは本チケットに添付しています。

また、このバックポートでmake rdocは以下のように速度改善するようです。

  • gc.c: Fixup around GC by MALLOC.
    Add allocate size to malloc_increase before GC

    Reset malloc_increase into garbage_collect()
    for preventing GC again soon.
