The nmap on your system either tries to write to a memory segment marked 
read-only, or is trying to read from a memory segment that doesn't 
belong to it.

The kernel doesn't like that, so it sends the offending process (nmap, 
in this case) a segmentation violation signal (SIGSEGV), which roughly 
translates to a good kick in the fracas for fondling someone elses 
girlfriend. The fracas being sensitive and the kernel being mighty, this 
means an early night for nmap.
