    _______________________________________________________

Details:

after loading a variable from file, in place operations fail when executed
inside a script. The same operation is returns correct results when given in
an interactive shell. 

Example: 

address@hidden:~> cat script.m
load "x.mat"
x+=0

octave:1> version
ans = 3.8.2
octave:2> x=0
x = 0
octave:3> save "x.mat"
octave:4> clear
octave:5> script
error: script: A(I): index out of bounds; value 61 out of bound 1
error: called from:
error:   script.m at line 2, column 1
octave:5> x+=0
x = 0
