fphttpclient Chunk too big

I encountered some mysterious bug regarding fphttpclient, to
replicate:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TForm1.Button1Click(Sender: TObject);var  http : TFPHTTPClient;  strm
: TMemoryStream;begin  http := TFPHTTPClient.Create(nil);  strm :=
TMemoryStream.Create;  try    try     
http.Get('http://localhost/fonts.zip',strm);     
Memo1.Lines.Add('Successfully download '+IntToStr(strm.Size));   
except      on e: exception do Memo1.Lines.Add(e.Message);    end; 
finally    http.Free;    strm.Free;  end;end; 
The code above run just fine when used to download file directly
(fonts.zip), but when the URL is a result of a PHP script, for
example:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i <?php  echo
file_get_contents("fonts.zip");?> 
I got an exception says Chunk too big. Such problem doesn't happen
with Synapse. Any idea regarding this matter?

** Forgot to add, I use Lazarus 2.0.6 with FPC 3.0.4

What's the full message? It should tell the maximum chunk size
allowed.

Nothing, it just says "Chunk too big". The fonts.zip file size is just
a mere 3 MB.

Oh, I guess the changes weren't in 3.0.4. You can try 3.2.0rc1 or
trunk, I'm not sure what 3.0.4 has since I only use stable release for
bootstrapping, my daily compilation uses trunk.

Can you recommend stable release that should be safe to use in
production? I thought any download suggested in website announcement
should be stable version

Yes, those are the stable versions, which as of today are Lazarus
2.0.8 and (still) FPC 3.0.4.

But note that FPC 3.2.0 is already in the release cycle (with a first
Release Candidate that should also be quite "stable", though it may
have still some quirks to iron out) so you can start using it in
production, even if just to test your projects against it.
