Hi Moro,

I am happy to help with C++ here. You originally said that you wrap the Send in a try/catch, but that's not apparent from the code sample below.

Are you able to send me the full source code so I can see what it's doing, as well as looking at how you connect and manage the clients?

Hello Angus,

Thanks for your reply.

These are the number you provide in your changelog :

I do not handle any client since this management is internal to

The really only thing i do is to send String with SendStr :

mpWSocketServer->Addr = "";

mpWSocketServer->Port = mHostPort;

mpWSocketServer->Proto = "tcp";


And when i send data :

for (int i = 0; i < mpWSocketServer->ClientCount; i++)





I added the OnBGexception on both TWSocketServer and client :

void __fastcall TServerSocketEngine::ClientBgException(TObject   *Sender,

Exception *E,

bool &CanClose)


CanClose = TRUE;   // Goodbye client !


In the example i can read :

// This event handler is called when a client socket experience a background

// exception. It is likely to occurs when client aborted connection and data

// has not been sent yet.

Now, i first receive the Stack overflow Exception,

then the ClientBgException() is called with this Overflow,

and at least, a couple of seconds later, the program crash on an EAccess
Violation and can't be recovered.

C++ XE3 focus me on the line 16233 of the file OverbyteIcsWSocket.pas below
the line of begin :

procedure TCustomSslWSocket.Do_FD_WRITE(var Msg: TMessage);


     Len        : Integer;    // How much to send

     Buffer     : array [0..16383] of AnsiChar;

     NumRead    : Integer;

     NumSent    : Integer;

     Err        : Longword;


     if (not FSslEnable) or (FSocksState <> socksData) or

        (FHttpTunnelState <> htsData) then begin

         inherited Do_FD_WRITE(msg);



I really don't know what can i do anymore !

PS : Is it normal that i can't compile ICS in release mode ?
