*Created by: priteshacharya* zctx_destroy hangs on both czmq 2.0.3 and 2.1.0 Zmq version: 4.0.3 I'm using windows build of czmq Both the zmq and czmq are built as DLL. #include <czmq.h> int main (void) { zctx_t *ctx = zctx_new (); void *socket_ = zsocket_new(ctx, ZMQ_PUSH); zsocket_connect(socket_, "inproc://collector"); zsocket_destroy(ctx, socket_); zctx_destroy (&ctx); return 0; } However there is no problem on linux.
