Hello,

I have a problem with the ping utility on Cygwin: it keeps crashing with segmentation fault.  I've checked that all my packages (including Cygwin core)
are up to date.  What am I missing?  At any rate, I guess it should not have crashed ungracefully if it needs something it doesn't have (like a permission); instead, if should have said so and bail out with an error exit code rather than a stackdump (attached).

Thanks,
Anton Lavrentiev

P.S. ping -h works; ping with any IP address -- crashes

$ ping 192.168.1.1
