1. machine exception in file.e

The program ran for 3 days, then crashed with the ex.err on 

http://pastebin.ca/1017034

Platform is winxp-sp2. I opened a dox box on that dir,and did a listing >
dir.txt, which is 3,634,889 bytes long, my average filename len seems to be 44
chars. Dir size is 254,305,792 bytes, 43,989 files, 0 folders. The last filenames
written look fine, i can open the dir in Textpad, get a listing, and open the
files.

So what happened?

Originally I thought it had to do with allocating space for name or for the
return value of machine_func(), but maybe something within machine_func(M_DIR)
itself?

I don't have the source code handy right now.

About what? Oh....
I don't know. I added a trace:

junk = dir(directory)
  if atom(junk) then
trace(1)  

so i could see when it happens, but it's all been legit so far. 

It was gigabytes way into the 15gig file, and since Winxp and *nixes have a
48bit series of extensions to the file operations Eu uses, praps the blockbuster
v4.0 could offer these as fall thrus if the new conditional code detects the OS
has them?
