STL列表代码在VC ++ 2005中触发断言，但不在VC ++ 2003中触发。 [英] STL list code fires assertion in VC++ 2005, but not in VC++ 2003.

问题描述

我从正在检查的列表迭代器中得到一个断言。

对NULL。这在VC ++ 2003（v7.1）中没有发生。在这些版本之间是否已经对STL进行了更改？b
应该知道哪些？我应该检查的任何资源？


谢谢，

你为什么这样做？

可能。实际上，非常有可能。

我正在从列表迭代器被检查中得到一个断言：

对NULL。

你为什么这样做？

因为我有一个函数来报告元素是否在
列表中。如果是，则返回该元素的迭代器。如果它不是
，那么它返回NULL。


这个坏吗？它在VC ++ 2003中运行良好。但是，

STL列表类的内部似乎不再喜欢它了。

我记得很久以前读过一些东西，他们已经做了一些

的变化。不过，我似乎找不到合适的资源。

我应该检查的任何资源？

手册是什么？ C ++标准？我不认为这是公开的

可用。

I''m getting an assertion fire from a list iterator being checked
against NULL. This did not occur in VC++ 2003 (v7.1). Are there
changes that have been made to the STL between these versions that I
should know about? Any resources I should check into?

thanks,
Jason

Why are you doing that?

Probably. Actually, very likely.

against NULL.

Because I have a function that reports whether or not an element is in
the list. If it is, it returns an iterator to that element. If it''s
not, then it returns NULL.

Is this bad? It worked fine in VC++ 2003. But, the internals of the
STL list class doesn''t seem to like it, anymore.

I recall reading something a long time ago that they had made some
changes. I can''t seem to find a decent resource on this, though.

Any resources I should check into?

Of what manual? The C++ Standard? I don''t think it''s publicly
available.

Sorry, you mean the newsgroup FAQ, obviously, duh. I had forgotten
