8137678 memory blocks allocated : 258591549/258591552
5226767 memory blocks freed     : 142155109/142155112
2910911 unfreed memory blocks : 116436440
True heap size : 951812096
True free heap : 392917184
Should be : 462779048
Call trace for block $00007F57C456D680 size 40
  $000000000040071F line 29 of demo.lpr
  $0000000000400180

The last 3 likes repeated until the end of 300M log data!

Why when ITEM_COUNT is small, there is no memory leak, but when it is
large, there are so many leaks?
