Details:

In one of our scripts, we were caught by the same bug as discussed here (but I
could not find it reported):

http://octave.1599824.n4.nabble.com/loading-matrix-no-error-but-undefined-variable-td4662859.html

We use load in a try-catch construct in a loop, relying on load to report
errors properly.

Also for interactive usage, it must be confusing to miss proper error
reporting.

Buggy (since error situation not reported):


# echo 1 2 > testfile
# echo 3 >> testfile
# octave-3.8.2 --silent
octave:1> load( 'testfile' );
octave:2>


Known workaround: load( '-ascii', 'testfile' );

Expected (error situation correctly reported):


# echo 1 2 > testfile
# echo 3 >> testfile
# octave-3.2.4 --silent
octave:1> load( 'testfile' );
error: load: testfile: inconsistent number of columns near line 2
error: load: unable to extract matrix size from file `testfile'
octave:1>
