last commit id: f615b8f

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

[hgourvest]

I got it: EINVAL = 22

[hgourvest]

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?

[hgourvest]

BTW this is the Android permissions I use:

[hgourvest]

android.permission.INTERNET
android.permission.ACCESS_NETWORK_STATE
android.permission.ACCESS_WIFI_STATE
