There is someone here in Academic Computing who is investigating this error and how to make it go away. You see, CMU bought a whole bunch of pmaxen and then found out that Andrew didn't really perform on that platform. The shell would often spit out error messages when running an ATK program. It would also core dump at random times. It turned out to be a memory management bug in the kernal and a bug with the exec() system call. This "unaligned access" message apparently results from bad programming practice. I have a pmax in my office and I've never seen this message. Beats me. When we make the fixes that cause this message to go away, we'll report on the cause. Gary Keim ATK Group

Which malloc are you using? The standard DEC one, or the Andrew malloc? --david
