Yes, it works in bash for me, too. Tcsh does something that apparently
breaks with the new snapshot, but since I don't get any error messages, it's
hard to tell what that might be.
You're not really giving us much to go on. I've tried ping (both Windows and
Cygwin version) under tcsh and both work fine. And, the small snippet that
you cut/paste in your original bug report clearly showed that ping was
responding to CTRL-C.
I'm still using this snapshot (I've had no reason to stop until now),
and have hit this issue two out of the last five times running Cygwin
ping. The ping process is still visible in Process Explorer after
hitting ^C. There's no obvious difference between when ^C terminates
the process and when it doesn't.
I managed to duplicate this once a couple of days ago in a mintty/tcsh
process but I had a very hard time consistently hitting it. So I wrote
a test case which ran ping repeatedly in a loop under mintty while another
process killed it. Eventually, I could duplicate the problem in a few
minutes. There were two problems, one illustrated by the "sigwaitinfo"
mentioned in another thread and another caused by a race.
After making some changes to signal handling, I ran the test case for an
afternoon without issue.
The current snapshot has these changes.
With the current snapshot (20120816 17:19:27), I have problems with
emacs-X11.exe. When I start it under X (by typing 'emacs&' in an xterm
window), its CPU usage goes up to 50% and its window never displays.
The attached file gives the result of attaching gdb and giving the
command 'thread apply all bt full'.
I reproduced this running emacs under mintty, but it took longer for it
to happen.
The problem doesn't occur with the 20120815 snapshot.
