“指定给 RtlFreeHeap( 06450000, 08387460 ) 的地址无效” 是什么意思?意思是?

有时我的 Delphi 程序会随机崩溃。我的程序停止,调试器输出:

指定给 RtlFreeHeap( 06450000, 08387460 ) 的地址无效

这是什么意思?什么可能导致它?

这是CPU Inspector停止的地方:

77BA0845 C6052582BD7700 mov byte ptr [$77bd8225],$00

请注意,它们是非常随机的(对我来说)。有时它们根本不出现。

我正在使用 Skype 的 Skype4COM.dll - 但没有来源。

如果您需要它,这里是代码。我已经评论了大多数 Synchronize 调用,因此您知道它们的作用。

Sometimes I experience random crashes in my Delphi program. My program halts, and the Debugger outputs:

Invalid address specified to RtlFreeHeap( 06450000, 08387460 )

What does that mean? And what can possibly cause it?

This is where the CPU Inspector stopped:

77BA0845 C6052582BD7700 mov byte ptr [$77bd8225],$00

Please note that they are very random (for me). Sometimes they don't appear at all.

I am using the Skype4COM.dll from Skype - there's no source though.

In case you need it, here is the code. I have commented most of the calls to Synchronize, so you know what they do.

Najem 是对的,这是因为你的堆已损坏。为了更容易调试,您应该启用 PageHeap,同时使用调试 CRT(或调试 delphi 运行时) )尽可能多,直到你找出是什么破坏了你的记忆。

很多时候,损坏可能只会溢出几个字节。然后您的应用程序可以在很长一段时间内正常运行,因此您直到很久以后才会注意到任何错误(如果有的话)。

当您寻找内存损坏错误时,请尝试干净地退出应用程序,不要只是停止调试器,当您的进程退出时,它应该“触及”之前分配的大部分内存,这将使您有机会检测到故障。

Najem was correct, it is because your heap is corrupted. To debug it easier, you should enable PageHeap, also, use the debug CRT (or debug delphi runtime) as much as possiable until you find out what's corrupting your memory.

A lot of the time, the corruption may only spill over a few bytes. Then your application can run fine for a very long time, so you will not notice anything wrong until much later, if at all.

Try to exit your application cleanly when your looking for memory corruption bugs, dont just stop the debugger, when your process is exiting, it should "touch" most of the memory it allocated earlier and it will give you a chance to detect the failure.
