[zeromq-dev] yet another problem with ZMQ_P2P

[Pavel Gushcha]

I know, that P2P is not in release, i want to help to debug it,
because i wrote big piece of code and don't want temporary rewrite it
with ZMQ_DOWNSTREAM/ZMQ_UPSTREAM sockets :-)

I attached simple test program, that demonstrates some problems (or
may be i missed something in my testapps):

test1.c illustrates simultaneous sending messages from first app (run
it by "test1 bind") to second (run it by"test1 connect"), and second
to first. First app crashes with messages:

msg 0
.....
msg 35
Bad address
msg 36
msg 37
nbytes != -1 (tcp_socket.cpp:197)
msg 38
msg 39
msg 39
Segmentation Fault

error like "nbytes != -1 (tcp_socket.cpp:197)" i see frequent in zmq1.
This is because my apps are connected trough relative slow, unstable
network. As i understand, this error occurs when connection is dropped
while sending/receiving messages. Could you fix this behaviour please
in zmq1/zmq2?

second application crashes too:
msg 0
.....
msg 45
msg 46
Segmentation fault


test2.c illustrates sending messages from first application and
receiving in second. First application crashes as in test2, second
application crashes with different error:
msg 0
Cannot allocate memory
rc == 0 (zmq_decoder.cpp:100)
Segmentation fault
