I know about new.

But I really just want a pointer to some amount of storage. I have to
pass it to som assembly routines. This routines cannot benefit from the
bounds in the array representatio. They would even overwrite them. And
I have to worry about space. The here useless bounds would cost me at
least 1MB.

Not possible. Perhaps I have to use malloc.
