Thanks. I think
- if (n < 10 || str[n - 1] != ')')
+ if (n < 10 || !n || str[n - 1] != ')')
would also be enough to prevent the segfault. However the issue, that
can be seen in the backtrace from Mike Montour is that atcmd_done()
has sent a random string to network_opers_cb(). In the log we can see
that the response from modem was normal text, but network_opers_cb()
contained rubbish characters and this is what caused the segfault. I
haven't found out why this happened.
