Summary: save(...,all) can't be reloaded

Initial Comment:
(discovered by Peter Ulrich Kruppa)

save("file",all)$
loadfile("file")$
  => Load failed

The problem is that the symbol DVA (used in NUSUM) 
has a property which is a compiled closure (a translated 
mmacro), which is not printable.

The workaround is to kill DVA before saving.

The problem is some interaction between Translate and 
Save which I don't have the time to track down.

I can't reproduce this problem. LOAD("nusum"); SAVE
("/tmp/foo.save", all); LOADFILE ("/tmp/foo.save"); 
succeeds, both for Maxima 5.9.1 official release on cmucl,
and 5.9.1 cvs on clisp (both on linux).

Examining /tmp/foo.save shows that DVA is present in the
save file.

Since I didn't have the time to find out what dva is and
what it does, here another simplicistic workaround:
open the session file with the editor of your choice and
delete all the  stuff that comes _after_ your last input,
probably something like:
(DSKSETQ $C6 '(($SAVE) |&session02| $ALL))
(ADDLABEL '$C6).

loadfile(...)
will work correctly then.

Peter Ulrich Kruppa
