      Description

        The expected_region_bm and expected_card_bm BitMaps used by VerifyDuringGC are allocated on the c heap on each call to cleanup(). The destructor of BitMap does not free the memory unless free_in_destructor == true is set for the ArrayAllocator backing the BitMap

        Suggested fix is to allocate the Bitmaps on the resource area of the VMThread executing the safepoint.
