Michael asks

"1) Unchecked_Conversion into a fixed size array.  (And if I do this, how
do I get the array bounds set correctly?)

2) Pass Record'Address and Record'Size into a subprogram.  Inside the
subprogram, declare an array of the appropriate size, located at the
appropriate address.  (have prototyped this one, and it works.)
"

method 2 is fine, be sure to use object'size and not type'size when
you do this (they can be different).

method 1 will also work, just declare a local subtype of the appropriate
size for the array, so that the sizes match, you can use 'Size of the
record object to compute the right bounds for the target array subtype.
