It was initially used to "prove" that RISC processors were more buggy than CISC, but the explanation turned out to be that the operating systems on RISC machines (which have to do more interesting work handling traps) were more buggy. I would be interested to know the results of running crashme on a BSD machine without a floating point processor - floating point emulation is a fine area for bugs. -- Richard -- Richard Tobin, HCRC, Edinburgh University R.Tobin@ed.ac.uk "We demand guaranteed rigidly defined areas of doubt and uncertainty" - HHGTTG
