Same problem in =net-analyzer/nmap-7.91-r1 as well. In older versions it works fine. How to reproduce: In first terminal: ncat --no-shutdown -t --keep-open -l -U ./testsocket In second terminal: ncat -U ./testsocket --sh-exec "echo -e '123'" fails with segfault error (segmentation fault). There no something strange in strace. Compiled with USE: ncat nping nse ssl
