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.

I just pushed a patch supposed to fix this issue. The bug is actually
worse and potentially affects more than just ping. Every time a socket,
socketpair, or accept call fails for some reason, there's a potential
SEGV. Oh, boy, oh boy.
I've just uploaded developer snapshots to https://cygwin.com/snapshots/
Please test.
I think this qualifies for a 2.11.2 release pretty soon...
Thanks,
Corinna

Tested for ping on both x86_64 and x86. Solved.

Thanks for testing, but we need more testing for normal network
operations, too. I'm going to push out a test release in a few
mins.

I wonder if that explains occasional curl coredumps?
