Access violation at address - InternalReceiveINDY(ATimeout: Integer): IStompFrame;

[samuel-cruz]

Hi @danieleteti,

When I try to authenticate with an invalid user, that server returns "Stopping tcp: //127.0.0.1:49367 because Failed with SecurityException: User name [guest] or password is invalid.", The InternalReceiveINDY statement if Result.Command = 'ERROR' then, the error "Access violation at address ..." is generated, because Result is nil due to the try except that exists in

class function StompUtils.CreateFrameWithBuffer (Buf: string): IStompFrame;

  try     ...   except     on EStomp do     begin       // ignore it       Result: = nil;     end;     on e: Exception of     begin       Result: = nil;       raise EStomp.Create (e.Message);     end;   end;

Since it is possible to identify the problem due to the exception below

---

Debugger Exception Notification

Project Project1.exe raised exception class EStomp with message 'Connection Closed Gracefully.'.

Break Continue Help

could replace the code

      if Result.Command = 'ERROR' then         raise EStomp.Create (FormatErrorFrame (Result));

per

      if Assigned (Result) then         if Result.Command = 'ERROR' then           raise EStomp.Create (FormatErrorFrame (Result));

Thank you!
