Wow I never heared about such option.
This are my results:
(compiled application is Win 32 bit)
How large are the memory blocks that you try to allocate.
Hard to say.
This happens inside TXMLDocument class as content is reading from file
in procedure ReadXMLFile.
May be that somewhere during processing occurs request for large block
of data.
(when I look at Resource Monitor as amount of memory is allocated I see
there jump in one moment . more than 500 MB at once)
it should be 2GB on 32bit and 4GB on 64bit Windows with
*IMAGE_FILE_LARGE_ADDRESS_AWARE*
There is a difference between the total amount of memory you can
allocate, and the maximum size of a single block of memory that you
can allocate. The latter is much smaller than the former,
I tried allocate at once 1GB and it succed.
I did simple program:
var
m: array[1..15] of pointer;
i: integer;
begin
for i:=1 to 15 do begin
m[i] := getmem(1024*1024*200);
fillbyte(m[i]^, 1024*1024*200, 0);
writeln(i);
readln;
end;
for i:=1 to 15 do begin
freemem(m[i]);
end;
end.
Which "confirms" limit 2GB, because it stops with run time error just
before 2GB boundary.
With {$setpeflags $20} under Win64 it can bypass 2GB.
So it leads me to conclusion, that somewhere inside ReadXMLFile must be
big request for memory block (may be for only short time), which
overcomes limit 2GB.
May be some kind of copy (assign) class instance to another ?
-Laco.
