The shell would crash when the
io:getopts()call got timeout when fetching state from the io process.Before
io:scan_erl_exprswould have returned{error,terminated}but as of introduction of explicit handling of when to save shell history, the failure is happening earlier.In this commit I add a check that makes
io:getopts()able to return error in the case the driver process is not responding.A check is also added on the shell side.
