I assume it is an interaction with mintty.
Many problems of that kind attributed to mintty are actually problems
with cygwin or especially pty.
Please test also with another terminal (xterm, rxvt, ...).
Also some more details could be helpful as I cannot reproduce the issue
(output of `type ping`, actual host pinged).

you are right is not a mintty only issue.
Same happens in xterm
$ which ping
/usr/bin/ping
$ ping 2.2.2.2
PING 2.2.2.2 (2.2.2.2): 56 data bytes
It sticks here forever, CTRL+C ineffective.
Process Explorer or Task Manager are needed to kill the process.
Also kill -9 PID is ineffective
On the old cygwin.bat (aka windows cmd)
CTRL+C is effective
64 $ ping 2.2.2.2
PING 2.2.2.2 (2.2.2.2): 56 data bytes
----2.2.2.2 PING Statistics----
2 packets transmitted, 0 packets received, 100.0% packet loss
