Question

sorry for the cryptic question title. I m having a strange problem and i have no idea why it is happening. Fortunately, the code involved is pretty simple. But beofre we get to it, let me briefly describe my app. It is a multithreaded app that serves a large amount of data. Something like an in-ram database. It is possible to have multiple "databases" in it and load/unload them at runtime. Now the problem is with the memory deallocation. Please see the code bellow (names of classes etc are changed, but this should not matter):

void SS::AllocTree( double*** pba, int i, int d, int b, int split )
{
    this->m_tree = new my_tree( pba, i, d, b, split );
}

void SS::DeallocTree()
{
    delete this->m_tree;
    this->m_tree = NULL;
}

每次都打电话到<条码>代谢;m=,节目坠毁。 st:

你可以看到,负荷/卸载是专为这项任务而单独建立的。不使用任何原始物品,不使用任何习俗肥皂或任何东西,在我的奶粉或我的节目中,没有新的/替代习俗操作者。我不知道为什么该方案要花在我的肩上,叫我删除,而是用新的文字,这不会发生。如果我改动<代码>DeallocTree(),照此办理:

void SS::DeallocTree()
{
    ::operator delete( this->m_tree );
    this->m_tree = NULL;
}

之后,所有东西都做了罚款。然而,这并不正确。是否应当对操作者有类似之处? 如何确保这一问题不会在其他地方发生? 为了完成这项工作,我还要附上DeallocTree(以下简称“DeallocTree”)版本的痕迹:

    msvcr90d.dll!operator delete(void * pUserData=0x00000000086f5fa0)  Line 45 + 0xa bytes  C++
    myprog.exe!SS::DeallocTree()  Line 58   C++
    myprog.exe!SSUnloader(void * arg=0x0000000008735f80)  Line 1038 C++
    msvcr90d.dll!_callthreadstart()  Line 295   C
    msvcr90d.dll!_threadstart(void * ptd=0x0000000008739d30)  Line 277  C

谁能向我解释一下这里正在发生什么?

EDIT:
To clarify:
my.dll is loaded dynamically - VS 2008 output: myprog.exe : Loaded C:*Debugmydll.dll , Symbols loaded.
Note: i am correctly using debug version of the dll with debug version of my program and vice versa with release.
**my_tree is declared as: my_tree* m_tree; // the tree

cl似乎就在 calls子里。在“双轨”电话中,你注意到的是,它把各种功能直接删除,等等。在分配中,分配工作由mvcr90d.dll执行。

您的旗帜是悬挂您国旗的国旗/MDd(或释放/MD),而右翼/MTd(或释放/MT)。将它们交给/送交(或释放/释放)以及你的问题将消失...... 基本上,你会把电话拨打到复方车上,而不是试图用两种不同的方式打听。
