Actually, I think it is more of a feature(?)
I first hit this with GNAT 3.15p (Linux). I think the explanation
was that the "new" was allocated on the stack when the data weren't
being kept after the function returns. It's called "optimization",
apparently. I had to resort to various tricks to get it to use
heap allocation instead. (making the size non-static might help.
Calling malloc instead works.) Very messy.
