This is not a valid implementation for arrays. There was an
explicit ACVC challenege from a compiler that did this and
blew up on one of the tests, and the protest was rejected.
Compilers should not allocate maximum space for variable
length arrays.
Now it is reasonable to do this for very small arrays for
some definition of very small, but to cause stack overflow
from this approach seems quite definitely a bug to me.
