Delphi/DBExpress导致内存泄漏

使用FastMM,我已经关注了内存使用情况的屏幕截图.我不完全确定如何读取该表,但看起来有些东西已经分配了296463552个字节(0x100fb000,这是“幻数”？)三次.

有任何想法吗？有没有办法跟踪非Delphi-MM内存分配？

我正在使用Delphi 2007和FastMM 4.96.

编辑：

我使用IMallocSpy编写了一个小助手类来跟踪COM内存分配.这是我得到的摘录：

所以,问题似乎是在数据库连接中.我正在使用来自Upscene的Firebird 2.1,DBExpress和InterXpress for Firebird驱动程序.

这似乎分析了类似的问题,至少重点在于这里：http://www.yac.com.pl/mt.texts.sqlexpr-2.en.html
