A little more than that. A make world would NOT EVER >complete on such a CPU. DG has demonstrated this bug, and described it to >the list. He has a K6 that will not complete a make world ever. At the >time, he could not even return it. It's important to remember that sig-11's and other such failures during make worlds are not the problem, but the symptom that there are serious problems. The build errors show up there because it's highly visible. What you don't see for every visible failure are potentially incorrect opcodes being written to object files, potential mis-fetched VM pages resulting in panics or crashes, possibly only after seriously corrupting a database or your filesystem, or other such creeping- death problems. ----------------------------------------------------------------------------- Michael L.
