Comment (by cameron.k.ward@…):

 I ran into this using 1.47 yesterday

 I was in debug mode VS2010.  I needed a pretty large receive buffer for a
 TCPReceiver.

 The first enum caused a stack overflow error.  Reducing the size stopped
 the error.

 Release mode did not complain about either size.

 struct TCPRawData{
         void* pParent;

         this blew the stack - enum{max_length = 1048576};

         this was fine - enum{max_length = 500000};

         char buffer[max_length];

         int bytesReceived;

         TCPRawData(void* parent):
         pParent(parent){}
 };
