Override Stack Allocate?

[coder_lol]

class A
{
};


int main()
{
A a; //Allocated on the stack.
}

Can I override the allocator for "a" to put a on the heap? I have a
problem where if my thread is killed asynchronously, the stack does
not get unwound, so I'd need everything to be on a heap I can control
and free.

Thank-you,

There's no way to do what you are asking for, a is on the stack and
there's nothing you can do about it.

You could do this though

class A_data
{
...
};

class A
{
A() : ptr(new A_data) {}
A_data* ptr;
};

int main()
{
A a;
}

Now class A is in effectively just a pointer to some data which has been
allocated on the heap.

If U want to store your obj in heap not stack,why not use something
like
A *a = new A();

If the stand new and delete operator do not comfort u,
you can also implement your own.addational your thread lock model on
memory.

Well, the "shell" of A would still be on the stack and not deallocated
properly.

Yes that is true.

Here's a suggestion, instead of asking questions about what you think
might be possible solutions to your problem, just describe your problem
in detail and with precision and then ask for any solutions.
