Hi, Sorry for the slow response.
So there are some problems with your test case. - zmq_send in ZMQ/2.x sends a zmq_msg_t structure, not a memory buffer - the ROUTER socket will return an identity blob as first part; you cannot print this as a string When I fix these problems and run the test case, it crashes as follows: Assertion failed: buffer_size == header_size (stream_engine.cpp:484) Which is issue 569, https://zeromq.jira.com/browse/LIBZMQ-569. I'll cut a new stable release with this fix. In the mean time you can build the stable version from https://github.com/zeromq/zeromq4-x -Pieter On Fri, Nov 22, 2013 at 4:05 PM, 舒友村 <[email protected]> wrote: > Hi , The following is my test case. > The peer installed zeromq2.2: > int main (void) > { > // Socket to talk to clients > void *context = zmq_init (1); > void *responder = zmq_socket (context, ZMQ_DEALER); > int rc = zmq_connect (responder, "tcp://10.10.19.154:5555"); > assert (rc == 0); > > char buffer [10]; > zmq_send(responder, "hello", 0); > sleep(10); > return 0; > } > > The peer installed zeromq4.0.1 > int main (void) > { > void *context = zmq_init(1); > void *responder = zmq_socket (context, ZMQ_ROUTER); > int rc = zmq_bind (responder, "tcp://*:5555"); > assert (rc == 0); > > while (1) { > char buffer [10]; > memset(buffer, 0, 10); > zmq_recv (responder, buffer,10, 0); > printf ("%s\n", buffer); > sleep (1); // Do some 'work' > } > return 0; > } > when connecting ,the crash happened in the peer which installed > zeromq4.0.1..Just like the following. > Assertion failed: buffer_size == header_size (stream_engine.cpp:485) > Aborted > Thanks... > > > On Fri, Nov 22, 2013 at 8:12 PM, Pieter Hintjens <[email protected]> wrote: >> >> OK, can you show us some very simple code that causes the problem for >> you?
