[twsocket] AccessViolation in TCustomWSocket.Receive (updated !)

2009-10-22 Thread Max Terentiev 

Hi,

Few weeks ago I notice random AV in TCustomWSocket.Receive
(see my message below).

Arno Garrels answer to my question:


BCB6 is no longer supported since ICS V6.
ICS-V6 for Delphi 7 / C++Builder 2006 to Delphi/C++Builder 2007 ICS-V7 for 
Delphi 7 / C++Builder 2006 to Delphi/C++Builder 2010


So, I move my app to BCB2007.

But.. I notice same problem: time to time I have AV in
TCustomWSocket.Receive !

My app is a little proxy-checker and problem happens on
connect to target host using socks proxy.

Anybody notice same problem ?

p.s. All works fin with ICS 5/BCB6 ! I notice this problem only
after upgrading to ICS v6.

Hi,

I move my app from ICS v5 to v6 and notice randomly AV
in TCustomWSocket.Receive:

function TCustomWSocket.Receive(Buffer : TWSocketData; BufferSize: 
Integer) : Integer;

begin
   Result := DoRecv(Buffer, BufferSize, 0);
   if Result  0 then
   FLastError := WSocket_Synchronized_WSAGetLastError
   else
   { Here we should check for overflows ! It is well possible to }
   { receive more than 2GB during a single session.  }
   { Or we could use an Int64 variable...}
   FReadCount := FReadCount + Result;  AV Here !
end;

AV always at FReadCount := FReadCount + Result; line.

My app use TSmtpCli in async mode and PingThread by
Angus Robertson. IDE = BCB6.

I never notice this problem with ICS v5.

Maybe I must update some my code to avoid problems with V6 ?
