Hi all - 

Having nmap core dump issue with the following setup:

First off here is my basic nmap command and core dump error:

# nmap 192.168.10.10

Starting Nmap 4.65 ( http://nmap.org ) at 2008-06-25 15:07 EDT
Assertion failed: diff <= interval, file timing.cc, line 352
Abort - core dumped

...snip...

Hey Tony, I think this issue was fixed in SVN a few days ago (log
below).  Go ahead and give the SVN copy a try.

Modified:
   nmap/timing.cc

Log:
RateMeter::update() used to abort if the new time was earlier than the old time.  But on my SMP Linux 2.6.20 system, 
I've been doing large-scale scanning and I'm getting very occasional values like "now=1214173867.8027; 
last_update_tv=1214173867.8065".  Unless I'm missing something, I think my gettimeofday may have decreased by 38 
microseconds.  Perhaps due to SMP and the old kernel.  Anyway, I changed it so that decreases of up to 1 millisecond 
just give a warning (one-time) rather than abort Nmap.
