I recently installed 1.7.29 on a new Win7/64 laptop. Every day or so, I
get a "fatal error" dialog from emacs-w32. It asks me if I want to debug
it, but I'm not sure what info I could pull from gdb that would be useful.
A gdb backtrace might or might not be helpful. I would start with other
things first (see below).
Is this a known problem?
No.
Is there any useful information I could provide?
Since this is a new computer, my first suggestion would be to check the
BLODA list (http://cygwin.com/faq/faq.html#faq.using.bloda). If that
doesn't help, please make a more detailed report, following the
guidelines here:

(Sigh. It died again while I was writing this note.)
Ok. I have McAfee on this box. Note that we've had McAfee installed on all
laptops here for quite a while, including my older Win32 box, which I didn't
see this problem on.
Are you sure there's nothing else? Windows Defender maybe?
I'm attaching the cygcheck.out file. I only elided my laptop hostname.
Nothing jumps out at me in the cygcheck output.
I followed the instructions for creating a backtrace (running "gdb -p <emacspid>" before clicking YES, and
then "continue", and then "bt"). However, it just said "No stack.".
You might have to run emacs under gdb and put a breakpoint at
emacs_abort in order to get a useful backtrace. But I'm not sure it's
worth putting a lot of effort into debugging emacs-24.3 at this point,
because emacs-24.4 is already in its pretest phase. I'm traveling right
now, but when I return in about a week I'll build the current pretest
version for you to try.
One other question: Can you find a way to reproduce the problem, or does
it just seem to happen randomly?
Ken
