Nmap Bug

Hello,I discovered a nasty bug in nmap while attempting to scan a large network. The reverse DNS was being done entirely through the /etc/hosts file on a Linux RH 6.2 system. We required the exact hostname to be returned from nmap via reserve lookup.
The problem was troubleshoot and fixed on nmap version 6.25. To correct the problem the source file "nmap_dns.cc" was modified:
#define HASH_TABLE_SIZE 256 was changed to #define HASH_TABLE_SIZE 4096I may go back and change the routine further to make the hash dynamic but this appears to not fine for our use of nmap.
Nmap is a great tool, please continue the great work. Please feel contact me if I can be of any assistance.
