[fpc-pascal] Problem with heaptrc

I use heap trace utility to see if there are memory leak in my program.
The source is here:
My problem is, at the beginning of the main program, I have a costant
ITEM_COUNT = 5000000;
If I set ITEM_COUNT to a small value, say 50 or 5000, everything is OK, no
memory leak. But with the above value, it will cause HEAPTRC to fall in an
endless loop, generating messages like:
Call trace for block $00007F41693AA680 size 40
$000000000040071F line 29 of demo.lpr
While line 29 is this:
27 for i := 0 to ITEM_COUNT - 1 do begin
28 for j := 0 to 4 do key[j] := $deadbeef + i + j;
29 h.Add(@key, SizeOf(PtrUInt) * 5, Pointer($deadbeef + i));
Could anyone tell me why heaptrc will fall in an endless loop, and does my
program have memory leak?
