Emacs freezes occasionally in such a way that sending it a DebugBreak
(see <https://cygwin.com/ml/cygwin/2006-06/msg00321.html>) has no
effect, and I have to kill it from the Task Manager (so I can not get a
backtrace).  When Emacs is in this state, it does not redraw its frames
when brought in focus.

In GNU Emacs 24.4.51.3 (x86_64-unknown-cygwin)
  of 2014-10-30 on [local build], Cygwin 1.7.33

Does it consume any CPU?

Can you attach GDB to Emacs when it is in such a state?  If not, can
you observe any activity of its threads via Process Explorer?

Not when I last checked, but I did not check last time it occurred, so 
I will check next time.

I have been always running Emacs under GDB, so yes.  I forgot to attach 
the GDB output in my original report; it is at the end of this 
paragraph.  When Emacs freezes, nothing is printed in the terminal 
(either by GDB or Emacs).  I also forgot to mention the version of Emacs 
I am using: from git branch emacs-24, commit 1500355.

GNU gdb (GDB) 7.8
This GDB was configured as "x86_64-pc-cygwin".
Reading symbols from ./emacs.exe...done.
SIGINT is used by the debugger.
Are you sure you want to change it? (y or n) [answered Y; input not 
from terminal]

Thanks.

OK, but for this kind of problems, it is best to run Emacs outside
GDB, and when it hangs, attach GDB to it.  In most cases, attaching a
debugger will interrupt whatever Emacs is doing, although in this case
it might not, as you said the DebugBreak program didn't.  But it's
worth trying.

That was 5 years ago.  Are you still seeing this on a recent version of
Emacs?

More information was requested, but none was given within 4 weeks.
Since it seems like we need more information, I think it's unlikely that
we'll make any progress here at this point.

I'm therefore closing this bug.  If this is still an issue, please
reopen the bug report.

Best regards,
Stefan Kangas
