It seem to be an unexpected error code that is not in this list:

    errno_assert (errno == EAGAIN || errno == EWOULDBLOCK || errno == EINTR
                  || errno == ECONNABORTED || errno == EPROTO
                  || errno == ENOBUFS || errno == ENOMEM || errno == EMFILE
                  || errno == ENFILE);

unfotunately the error code is not logged. what should I do to log the error code? And what is the point to make it crash in this case?

The fist line is quite interesting and could be related:

I compile for Android Api level 16, and I need to undef these compiler options:

define ZMQ_HAVE_ANDROID 1

undef ZMQ_HAVE_PTHREAD_SET_AFFINITY

undef ZMQ_HAVE_TIPC

undef ZMQ_HAVE_GETRANDOM

undef ZMQ_HAVE_SOCK_CLOEXEC

undef ZMQ_IOTHREAD_POLLER_USE_EPOLL_CLOEXEC

I got it: EINVAL = 22

hgourvest commented 5 years ago

The problem occur when I desactivate and reactivate the wifi on my phone, if I add EINVAL to the list it not crash anymore, but I don't know it is the right thing to do. Any advice?

BTW this is the Android permissions I use:
