Custom memory allocations

[madrenegade <madrenegade@...>]

I am using Lua in my game engine and want to use my own memory allocator.
The problem is that Lua seems to call the allocation function with 
pointers that are not managed by my own memory manager.

Is this behaviour wanted? Is there a way I can work around this behaviour?

Here follows the output which shows how the allocation function is 
called at runtime. The very last call
fails because the pointer is unknown to my memory manager.
