Details:

This bug is present in both 3.2.3 and 3.3.54+. I tried to execute the test
found in liboctave/CMatrix.cc

assert([1+i 2+i ; 3+i 4+i ] * [5+i ; 6+i], [15 + 14i ; 37 + 18i], 1e-14)

It fails,  and the funny thing is:
[1+i 2+i] * [5+i ; 6+i]
ans =  15 + 14i %#  OK
[3+i 4+i ] * [5+i ; 6+i]
ans =  37 + 18i %# OK

[1+i 2+i ; 3+i 4+i ] * [5+i ; 6+i]
ans =

   17 + 11i
   39 + 11i

Just plain wrong. 

Regards

Pascal
