Describe the bug I just updated NMAP from 7.97 to 7.98 and tried running NMAP scans. Upon running IPv6 types scans like TCPv6, Protov6, UDPv6 scans when scan about to finish it crashes with the error - Segmentation fault (core dumped). However upon downgrading to 7.97 this issue is not coming.

To Reproduce Steps to reproduce the behavior:

  1. Upgrade to NMAP 7.98
  2. Try this to run TCPv6 scan - " nmap -6 -sS -A -v --reason -p- -n -Pn -oA test_tcpv6_7.98 [ipv6] "
  3. Once scan about to finish this error will come - Segmentation fault (core dumped).

Expected behavior Error should not come and scan completes successfully. Just like it does in 7.97
