bug#11367: Crash: Windows 7 using egg

Sorry for the delay.  It stopped aborting at exactly the same place,
on multiple machines, with
and without -Q.  I tried a lot of combinations and it seems that
adding one more step, a C-n, does it.

The abort is sporadic during development, but this seemed to do it
every time.  Perhaps it
isn't as certain as I thought.

I'm impressed with your remote debugging ;)

My mistake.  I had to download mingw from scratch and install gdb,
etc. and forgot a step.

"posn-at-point" (0x88e448)
"mouse-avoidance-point-position" (0x88e744)
"mouse-avoidance-too-close-p" (0x88ea34)
"mouse-avoidance-fancy" (0x88ee38)
"apply" (0x88ee34)
"byte-code" (0x88f084)
"timer-event-handler" (0x88f4fc)

This original backtrace was without -Q, so the mouse avoidance setting
may be non-default.  Let me know if I should kill it and get a -Q

* Download the egg library from https://github.com/bogolisk/egg

  I am using the latest version.

* Create new git repository in an empty directory:

  $ git init

* Create readme.txt with "1st line\n" and commit.

  $ git add readme.txt
  $ git commit -m "initial commit"

* Append "2nd line\n" to the readme.txt file.

* Create two new text files with one line each:

  * file1 with "file1\n"
  * file2 with "file2\n"

* Start emacs while in repo directory: $ emacs -Q

  (You can start from any directory, but egg-status uses the current
directory.  Use can use
  any other method, such as cd or dired to set the current directory
to the repository

* Load the egg library: M-x load-file , then find egg.el

* M-x egg-status

  Splits window and creates status buffer on bottom.

* Put the cursor on file1 at the bottom of the status window.

  C-x o    ; switch to status buffer
  C-n ...  ; move to file1

* Press 's' to stage the file which will remove file1 from the bottom
section and create a new file1 section
  showing a diff.


* At this point it may crash.  If not, the cursor should be on the
file1 filename in the new
  section.  Press C-n once to crash.
