SUMMARY: DEC Pascal Debug Problem

I asked about a problem with the Pascal 5.2 compiler
not producing correct debug info:

% cat test.p
program test(input,output);

const Max = 28;

type ItArrayD=array[1..Max] of double;
        ItArrayI=array[1..Max] of integer;

var age : ItArrayI;
        meanD, varV : ItArrayD;
        i : integer;

begin
        for i := 1 to Max do
        begin
                age[i] := i;
                writeln(age[i]);
        end;
        writeln('end');
end.

% pc -g -C all test.p -o test
% dbx test
dbx version 3.11.6
Type 'help' for help.

(dbx) stop in main
[2] stop in TEST
(dbx) run
[2] stopped at [TEST:13 ,0x1200018d0] for i := 1 to Max do
(dbx) whatis age
var AGE : array[28..32] of 86015..1; <*** you must be joking !!
(dbx) whatis varV
var VARV : array[1..28] of double;


 
I received the following from the DEC Pascal people:

Thanks for you help
