将项目从Delphi 2007升级到Delphi 2009后,我收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来跟踪它,这是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
有时我得到这个：
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弄清楚导致内存泄漏的真正原因？
解决方法
这个内存泄漏是由Delphi bug QC
#67709引起的
它是由最后一次Delphi 2009更新修复的,难怪我无法修复它.
