I figured out what caused the panic and
Segmentation violation and thought the community might want to here the
solution.
Here
is how I narrowed the problem down. I had two identifical files, each in
different directories on a hard drive. In one of the directories a 'dir'
resulted in a panic, in the other director it didn't. One file I had downloaded
from a remote server, the other was copied from a DVD. A diff on the files
gave me no clues and absolute zero differences in the file. I then noticed
the file that caused a panic had a date of June
1905. (Created on a linux system without a battery to maintain the
clock gives us a default date that pre-dates modern
computers).
I used mingw to 'touch' the file
that was giving me problems, and no more panic! Problem solved.
(Unfortunately the files on a DVD can't be touched so easily, but a cheap
portable hard drive solved the problem of copying 12G of data to a place I could
touch them).

On a WinXP running
Octave 3.0.0 I wanted to get a list of the files on a DVD. I changed to
directory D:/ to access the DVD and a simple directory listing with 'dir' caused
this:
panic: Segementation
violation -- stopping myself ...
attempting to save
variables to 'octave-core'...
warning: unable to
open 'octave-core' for writing...
Octave completely
freezes up and I have to manually kill the process with task manager.
Any
suggestions?
