A lot of changes and fixes have been made in Cygwin since 1.7.9 has
been released, so we're looking forward to release Cygwin 1.7.10 soon.
Please test the latest developer snapshots at http://cygwin.com/snapshots/
which should have "Release Candidate" quality.
Here's an easily reproducible problem with the 2011-12-05
1. Download cygwin-inst-20111205.tar.bz2 .
2. Start mintty from the Cygwin Terminal shortcut.
3. tar -C/ -xf /path/to/cygwin-inst-20111205.tar.bz2
An hourglass appears and tar doesn't run. I'm on W7-64 if that
makes a difference.
Works for me. I just tried from mintty with bash as login shell as
well as with tcsh as login shell. I even left out the --exclude and
it worked ;)
Does that really occur reproducible on your machine, every try?
Yes. And I just tried twice more with the same behavior. Earlier
today I had a similar thing occur on a different machine, on which
the 2011-12-04 dll was installed instead of the 2011-12-05 dll. On
that machine (again W7-64), the mintty window simply disappeared
when I gave the tar command.
Hmm, that's weird.
The only other detail I can think of is that I started mintty by
right-clicking on the shortcut and choosing "Run as administrator".
Still works for me. That's puzzeling. Any chance to debug that?
Stracing, attaching with GDB, building your own debug-enabled Cygwin,
I ran the tar command under strace. I'm not good at deciphering strace
output, but you can see it here:
A few further observations:
- As the strace output shows, tar does in fact run, contrary to what I
originally thought; it's just that there's no indication in the terminal
that tar finished.
- When I finally get tired of waiting and kill mintty (and the
associated bash process) from another terminal, mintty leaves the
following stackdump on the desktop:

- Other mintty windows that are open become unusable. The title bar
shows "not responding".
Does any of this help? Should I be stracing mintty rather than tar?
