And on an x86 with 2.1.69 what happens? I suspect the problem is not in 
the functions you supplied but in the rand and randn functions from 
sourceforge.. These were fixed in the CVS on Feb 6, but no new 
octave-forge release has been made since. I'd suggest recompiling the 
stuff in octave-forge/FIXES and see if that helps...
