I recently came across a bug in nmap v 4.0.

The bug manifests itself when attempting to write output from a scan
with the -sV option set and the ignored port state for the output is
defined as PORT_OPENFILTERED.  Nmap will give an error stating that the
assertion on line 143 of NmapOutputTable.cc in the
NmapOutputTable::addItem function failed.

Thanks for the report.  I was able to reproduce this, and have
implemented this fix for the next version:

--- service_scan.cc     (revision 3050)
+++ service_scan.cc     (working copy)

+    svc->target->ports.addPort(svc->portno, svc->proto, NULL, PORT_OPEN);
     if (o.verbose || o.debugging > 1) {
       svc->target->NameIP(host, sizeof(host));
