<p class="MsoNormal">I noticed that calling inet:getstat/1 is a dangerous operation, as it can kill the whole VM if used inappropriately.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">It is easy to reproduce:<o:p></o:p></p>

<p class="MsoNormal"><span style="font-family:"Courier New"">Eshell V9.3 (abort with ^G)<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Courier New"">1> application:start(sasl).<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Courier New"">ok<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Courier New"">2> [inet:getstat(X) || X<-erlang:ports()].<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Courier New"">Failed to write to erl_child_setup: 9<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Courier New"">Crash dump is being written to: erl_crash.dump...done<o:p></o:p></span></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Without sasl, it doesn’t kill the VM, but the terminal gets into a faulty state and further work is not possible.<o:p></o:p></p>
<p class="MsoNormal">I know calling it on a non-socket is an erroneous action, but crashing the VM doesn’t seem to be the most appropriate consequence.<o:p></o:p></p>
<p class="MsoNormal">What do you think?<o:p></o:p></p>
