I am not a specialist of strace, but looking at the log file I found
this:
error: `ab' undefined near line 1 column 29
Which command did you use for producing the strace dump? In my
previous message, I suggested this:
echo 'a=[1 2; 3 4]; b=[5 6;7 8]; a*b' | strace octave
It looks like you typed 'ab' instead of 'a*b'. If this is the case, then
the matrix multiply bug was not exposed. Please, try it again.
