nmap: nsock_event.c:406: msevent_new: Assertion `msiod->state != NSIOD_STATE_DELETED' failed

[Abuse 007 <abuse007 () gmail com>]

Hi,

I'm getting a nmap: nsock_event.c:406: msevent_new: Assertion `msiod->state
!= NSIOD_STATE_DELETED' failed error which is terminating nmap when
scanning a range of addresses.

The command I'm using is: nmap -Pn -A --script 'safe and not broadcast*'
-oA nmap-x.x.x.224_27.`dt` x.x.x.224-255

dt is a script to print out the date-time in ISO format (i.e.
"20121112-153151")

I'm using the nmap from SVN Revision: 29188, on Ubuntu 10.04.2 LTS,
Linux 2.6.38 SMP i686.

Output: -

Starting Nmap 6.02 ( http://nmap.org ) at 2012-11-09 11:14 EST
Pre-scan script results:
|_eap-info: please specify an interface with -e

NSIOD_STATE_DELETED' failed.
Aborted


This was happening on an earlier revision, I tried checking out a later
SVN, recompiling etc. Still hitting the issue.

I search and found this post, http://seclists.org/nmap-dev/2012/q3/56,
which was fixed.

Is this a regression, or a separate issue?

Can nmap's error handling be buffed up to not abort the whole scan, but log
an error/warning instead. Also can more details about which session the
event/assertion is related to be included in the error message so that
users can skip over hosts or services that are causing the crash.

Any troubleshooting I can do? I'd prefer not to use a debugger, but will if
it helps. Will have limited time to test this target though.

Thanks,
Abu
