FWIW, I could reproduce it today with the latest Nmap from SVN.
Thanks a lot for taking the time to do this. Unfortunately, it looks like we will need a bit more info. It seems as though the nmap binary you used had debug symbols stripped. If you install with "make install" it will automatically strip the binary to save disk space. Unstripped binaries give a more detailed backtrace, including what line number of the file each frame is executing. If you get a chance, could you get another backtrace from an unstripped binary? The easiest way is probably just to re-compile and then run the scan with the nmap binary in the current directory before you make install it. I find the easiest way to tell if a binary is stripped or not is to use the file command: $ file ./nmap nmap: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.2.0, dynamically linked (uses shared libs), not stripped versus $ file ./nmap nmap: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.2.0, dynamically linked (uses shared libs), stripped Thanks again for your time!
