Re: Ping crashes
Hello, Anton. I'm a maintainer of ping package. Thank you for your report. Ping requires administrator privilege in windows OSs older than Windows 10 build 14926. In such OSs, ping should result in error: 'ping: Lacking privilege for raw socket.' However, with cygwin 2.11.0 or later, it seems that ping crashes with segmentation fault in the above case, as you reported. With cygwin 2.10.0, ping does not cause segmentation fault. I will look into this problem.
