Re: Challenging GotW 66's moral

Hello everyone,

In GotW #66, one of the moral is the exception handler of constructor
should not do any like resource free task. I do not agree. Here is the
quoated moral and my code to prove this moral will have memory leak.

Anything wrong with my analysis?

http://www.gotw.ca/gotw/066.htm

Moral #1: Constructor function-try-block handlers have only one
purpose -- to translate an exception. (And maybe to do logging or some
other side effects.) They are not useful for any other purpose.

[Code]
class A
{
private:

int* p;

public:

    A()
    try
    {
        p = new int[10];

        // there are some other exceptions here

    }
    catch (bad_alloc)
    {
        // do not delete since bad_alloc means memory pointed by p is
not allocated
    }
    catch (...)
    {
        // if we do not delete p, there will be memory leak
        // at this point, we are conflicting with Gotw 66's moral 1
        if (p) delete[] p;
    }
}
