ApplicationVerifierを使用してWin32アプリケーションを分析しようとしています。基本の下のすべてのカテゴリをチェックしました。したがって、次のコードでは、
// Function which unloads the DLL
int unloadDLL()
{
if(DLLHandle != NULL)
{
if(0 == FreeLibrary(DLLHandle))
{
// Failed to unload the DLL
return -1;
}
DLLHandle = NULL;
}
return 0;
}
アプリケーションベリファイアが停止し、次のようにスローします。
=======================================
VERIFIER STOP 00000903: pid 0x770: A virtual reservation was leaked.
04DB0000 : Leaked reservation address.
00825FC4 : Address to the allocation stack trace. Run dps <address> to view the allocation stack.
07870FE0 : Address of the owner dll name. Run du <address> to read the dll name.
04B00000 : Base of the owner dll. Run .reload <dll_name> = <address> to reload the owner dll. Use 'lm' to get more information about the loaded and unloaded modules.
=======================================
This verifier stop is continuable.
After debugging it use `go' to continue.
