        Description

        The AdaptiveFreeList<Chunk>::verify_stats method contains the following err_msg:

                 err_msg("FreeList " PTR_FORMAT " of size " SIZE_FORMAT
                         " violates Conservation Principle: "
                         "prev_sweep(" SIZE_FORMAT ")"
                         " + split_births(" SIZE_FORMAT ")"
                         " + coal_births(" SIZE_FORMAT ") + 1 >= "
                         " split_deaths(" SIZE_FORMAT ")"
                         " coal_deaths(" SIZE_FORMAT ")"
                         " + count(" SSIZE_FORMAT ")",
                         this, size(), _allocation_stats.prev_sweep(), _allocation_stats.split_births(),
                         _allocation_stats.split_births(), _allocation_stats.split_deaths(),
                         _allocation_stats.coal_deaths(), count()));

        The argument to coal_births is split_births, which will cause the error message in the assert to be wrong.
