使用Chromium Embedded时如何解决此内存泄漏？

Chromium Embedded的GuiDemo代码（https://code.google.com/p/delphichromiumembedded/）正在泄漏少量内存。数量不多，但是每次停止应用程序时都会从FastMM收到该消息非常烦人。我猜泄漏是在Chromium接口中。该单元具有“初始化”部分：

INITIALIZATION
 CefCache := 'cache';
 CefRegisterCustomSchemes := CefOnRegisterCustomSchemes;
 CefRegisterSchemeHandlerFactory('dcef', '', True, TFileScheme);

日志是这样的：

A memory block has been leaked. The size is: 20

This block was allocated by thread 0x1674, and the stack trace (return addresses) at the time was:
40455E 
4050A7 
409C1D 
405622 
4050DC 
4F0D7A 
406598 
406604 
40A6C3 
4F0E28 
764CEE1C [BaseThreadInitThunk]

The block is currently used for an object of class: main$174$ActRec
The allocation number is: 323

--------------------------------2014/10/5 17:11:33--------------------------------
This application has leaked memory. The small block leaks are (excluding expected leaks registered by pointer):
13 - 20 bytes: main$174$ActRec x 1

问题是我不知道main $ 174 $ ActRec是谁。演示所在的单元实际上称为“ main.pas”。但是没有其他称为“ main”的变量。
