I can't use alloca, because the stack-based allocation will be done in
the constructor and alloca will free the memory as soon as the

I'm working on dynamic memory layout manager. Simply put, it will
allow one to create and use struct types at run-time.
Normally, you create a struct at compile-time type by specifying an
ordered list of fields, each with its own type (basically a size) and
name.
You then access those fields by calling a compile-time evaluated dot
operator, which computes the address of the specified field given the
address of the struct.
What I'm trying to make is precisely that, except at run-time.
My question is: what is the best way of allocating such a structure on
the stack? It will, of course, have a dynamically known size.
alloca?

If that's the case, I don't know how you actually want this stack
allocation to work. The only way I see that you could do it would be
with dirty hacks making assumptions about the compiler, platform,
calling convention, ...
