Unhandled exception crashes the game : A heap has been corrupted

Hello,

I make a Windows game that uses named pipes to communicate with the outside. I can successfully receive data, but the game keeps crashing when I send ~5 messages (yes, 4 is fine but the fifth one makes everything crash, even if messages are identical.. I don't know why).

What happens is a small delay of a second and then the game just closes itself, with no information.

I tried :

• Running a "development build" standalone, but the error is not catched into the output log.

• Different ways of sending my message (ASync, normal, by disposing NamedPipeClientStream ...) unsuccessfull.

• Running from the Editor. In this case I can use Visual Studio to debug and I get the error

  "Unhandled exception at ...... (ntdll.dll) in Unity.exe: .....: A heap has been corrupted (parameters: ....)."

I have no idea what is happening here. My hypothesis is that unity's System.IO.Pipes is broken.

I would like to find a workaround or if possible to ignore this error. I am already using try-catch when sending messages and it seems like it does nothing. When running from the editor and debugging with VS, I was able to ignore the error and continue the execution. Maybe I can do that to automatically ?

Here is the send method I use now :

 public void send(PipeMessage message)
 {
     try {
         pipeClient = new NamedPipeClientStream(".", sendPipeName, PipeDirection.Out, PipeOptions.Asynchronous);
         pipeClient.Connect(timeOut);
         pipeClient.BeginWrite(message.bytes, 0, message.bytes.Length, aSyncSend, pipeClient);
     }
         catch (Exception e) {
     }
 }

 private void aSyncSend(IAsyncResult iar)
 {
     try
     {
         NamedPipeClientStream sApipeClient = (NamedPipeClientStream)iar.AsyncState;
         sApipeClient.EndWrite(iar);
         sApipeClient.Flush();
     }
         catch (Exception e) {
     }
 }
