Watch out for allocation of huge stack areas for aggregate assignments
to arrays...

e.g.:

type Large_Array is array (1..100, 1..10, 1..1000) of integer;
My_Large_Array : Large_Array;

procedure Initialise
begin
    My_Large_Array = (others => 0, others => 0, others => 0);
end Initialise;


will attempt to allocate a 4MByte or so block of stack to create an
aggregate before copying it to the global variable (My_Large_Array).
Green Hills claim it is *required* by the RM, but certain people who
were involved in writing the manual disagree!
