Can we just have struct inheritence already?

On 64 bit architectures you probably could write a custom malloc 
that will return a unique address outside the memory map for 
0-sized allocations. It would have to mark it in a bitmap so that 
it could be freed.

*shrugs*

But, I doubt that people actually do this often. Allocating 4-8 
bytes probably would be ok, so you could just redefine malloc as 
malloc(max(allocationsize,8)).
