发帖数: 45 | 13 I think an pair of overloaded new and delete functions could be pretty helpful
in many cases. It records each allocated/deallocated memory block and
the statement allocating/deleting it. After the main program is ended, it could
output the memory blocks which have not been released yet and the corresponding
statements allocating them.
Besides, we could cache the memory blocks if your program allocate/deallocate
small memory blocks frequently, and the performance fo the program could be
improved |

when you need to control the object instantiation, e.g. singleton.
if you don't allocate additional memory explicitly (via new), then no.
compiler will deallocate all implicitly allocated memory, e.g. subobject's
destructor will be executed. if you do allocate, then you will need to catch
whatever exception (using catch (...) ), deallocate whatever memory, then
rethrow the exception. |

node. #7 is about dealocating the memory for current tree node. That
deallocate function has actually been called before when you erased the same
node from ~Foo(). That's why I said it is the map node (not Foo) being
deleted twice.
Set a breakpint in stl_tree.h line 273 deallocate function and you will
observe it is called twice.

发帖数: 15689 | 19 估计是这样：s2分配在stack上，对foo的调用结束时s2被deallocate，但是s2被分配的
那段内存还没有被覆盖，对t的赋值导致在stack上为t分配内存，于是t就指向了s2原先

发帖数: 61 | 25 each function has its own stack.
When you call copy(), it creates a new frame and initializes s to &a, t to &
b. So s and &a points to the same memory location, but they are different.
After you assign s to t, both of them hold the memory location of a. When
you return, you are just returning the memory address of a, and both s and t
are deallocated.
c gets this pointer, and that's why it prints out 1. |

getchar();
free(mem);

起同样的进程，第一个进程在 free() 后的getchar()停住，
然后起足够多个同样的进程，在 malloc() 后的getchar() 停住，看会不会把第一个的

在2011年WWDC（苹果全球开发者大会）的一场与Objective-C相关的讲座上，开发者的
人生观被颠覆了。
作为一个开发者，管理好自己程序所使用的内存是天经地义的事，好比人们在溜狗时必
须清理狗的排泄物一样（美国随处可见“Clean up after your dogs”的标志）。在本
科阶段上C语言的课程时，教授们会向学生反复强调：如果使用malloc函数申请了一块
内存，使用完后必须再使用free函数把申请的内存还给系统——如果不还，会造成“内
存泄漏”的结果。这对于Hello World可能还不算严重，但对于庞大的程序或是长时间
运行的服务器程序，泄内存是致命的。如果没记住，自己还清理了两次，造成的结果则
严重得多——直接导致程序崩溃。

内存一样困难。所以Objective-C中的内存管理又增... 阅读全帖 |

2. Normally when you have tons of malloc and free and the data could be reused

compiler will deallocate the obejct for you if you are using new and
the constructor throw an exception, say

Compiler will first call (equivalently) operator new() then new (t) T(p).
If T(p) throws then compiler will call operator delete. You don't need to
do it explicitly. I remember Sutter once talked about this when suggesting
to write operator delete, see
