<p>Not sure if this is correct behavior or not.. When you try and access certain core variables in an event route it segfaults and crashes opensips.</p>
<p>if you can't access these core vars in event routes by design, maybe it should give a friendly error like "Cannot access variables within event routes"?</p>
<p>Steps to recreate..<br>
1. Create an event route like...</p>
<pre><code>event_route[E_UL_CONTACT_UPDATE]{
fetch_event_params("aor=$avp(aor)");
fetch_event_params("address=$avp(address)");
fetch_event_params("callid=$avp(callid)");
fetch_event_params("received=$avp(received)");
fetch_event_params("cseq=$avp(cseq)");
xlog("L_INFO","$si");
}
</code></pre>
<ol>
<li>Get a device to register a 2nd time/update the contact and with logging at full it will print out..</li>
</ol>
