Unless, perhaps it is an underlying hardware flaw, but it is capable of being masked by the operating system. Thanks to John M. Blasik (john@mlb.semi.harris.com) for running it on a 4/330 under SunOS 4.1, where it didn't crash. And to Vick Khera (khera@cs.duke.edu) for running on a 4/60 under SunOS 4.03, where it did crash.
