如何用fastMM追踪棘手的内存泄漏？
提问于 2008-11-07 11:52:02
在将一个项目从Delphi2007升级到Delphi2009后，我得到了一个未知的内存泄漏，到目前为止，我一直在尝试使用fastMM来追踪它，以下是fastMM堆栈跟踪报告：
A memory block has been leaked. The size is: 20
This block was allocated by thread 0x111C, and the stack trace (return addresses)
at the time was:
40339E [System.pas][System][@GetMem][3412] 534873 [crtl][_malloc]
56D1C4 [canex.cpp][MidasLib][DllGetDataSnapClassObject][3918]
56D316 [canex.cpp][MidasLib][DllGetDataSnapClassObject][3961]
56D5EE [canex.cpp][MidasLib][DllGetDataSnapClassObject][4085]
562D48 [DBCommon.pas][DBCommon][TFilterExpr.PutExprNode][1583]
408E46 [System.pas][System][DynArraySetLength][20464]
56D5EE [canex.cpp][MidasLib][DllGetDataSnapClassObject][4085]
408E92 [System.pas][System][@DynArraySetLength][20486]
528C1B [Forms.pas][Forms][TCustomForm.DoCreate][3260]
171A1A [GetRawStackTrace]
The block is currently used for an object of class: Unknown
The allocation number is: 302844有时我会得到这样的结论：
A memory block has been leaked. The size is: 20
This block was allocated by thread 0x111C, and the stack trace (return addresses)
at the time was:
40339E [System.pas][System][@GetMem][3412]
534873 [crtl][_malloc]
56D1C4 [canex.cpp][MidasLib][DllGetDataSnapClassObject][3918]
56D316 [canex.cpp][MidasLib][DllGetDataSnapClassObject][3961]
77DC921A [RtlAnsiStringToUnicodeString]
56D5EE [canex.cpp][MidasLib][DllGetDataSnapClassObject][4085]
7726B8F5 [GetProcAddress]
7726B907 [GetProcAddress]
589B1E [ossrv.cpp][MidasLib][DllGetDataSnapClassObject][3163]
56D5EE [canex.cpp][MidasLib][DllGetDataSnapClassObject][4085]
408E92 [System.pas][System][@DynArraySetLength][20486]
The block is currently used for an object of class: Unknown有没有更好的方法来找出导致内存泄漏的真正原因？

这个内存泄漏是由Delphi的一个bug，QC #67709引起的
它已经被Delphi2009的最后一次更新修复了，难怪我不能修复它。
