[zeromq-dev] bstarcli, Bad file descriptor returned, getsockopt

[hhusp house]

I built the czmq-stream-client.c and  czmq-stream-server.c and did an strace on the server.I got the same result (errno 9 returned by getsockopt).  (src/zsock.c:1524)Called by zsock_resolve (self=0x603da0)
The strace shows that first argument op getsockopt is not a valid socket. Should by 9 in this case.
20120 socket(PF_INET, SOCK_STREAM|SOCK_CLOEXEC, IPPROTO_TCP) = 920120 setsockopt(9, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 020120 bind(9, {sa_family=AF_INET, sin_port=htons(5555), sin_addr=inet_addr("0.0.0.0")}, 16) = 020120 listen(9, 100)                    = 020120 getsockname(9, {sa_family=AF_INET, sin_port=htons(5555), sin_addr=inet_addr("0.0.0.0")}, [16]) = 020120 write(6, "\1\0\0\0\0\0\0\0", 8)   = 820120 write(8, "\1\0\0\0\0\0\0\0", 8)   = 820120 getsockopt(888436816, SOL_SOCKET, SO_TYPE, 0x7fff68fa93d8, 0x7fff68fa93d4) = -1 EBADF (Bad file descriptor)

Platform: CentOSzeromq-4.1.2czmq-3.0.2

I built the bstarsrv2 and bstarcli from the C examples zguide tree(git clone --depth=1 git://github.com/imatix/zguide.git)
When I look at trace a noticed the error returned by getsockopt:
getsockopt(2300165744, SOL_SOCKET, SO_TYPE, 0x7fff9f74b3bc, 0x7fff9f74b3b8) = -1 EBADF (Bad file descriptor)
sock_type is -1
