Rule 22.1: object declaration and deleted timing

[andy_su]

Hi, I have a question about object declaration and deleted timing.
I need to declare an object in constructor and release it in deconstructor, because the object will be reused frequently, but it is not compliant on MISRA C 2012.
The sample code as below.
Could you give me any hint to solve it?
Thanks.

Code:

ABC::aa(const Arguments& args)
{
    pImpl = new ABC::impl(args);
}

ABC::~aa()
{
    delete pImpl;
    pImpl = NULL;
}
