Bug#215831: CPU Detections code still buggy for some P4's ?
What is the bug here? Dose the app break the CPU detection code? AFAIK
The code has worked fine for a long time and has not been changed. There
should be a signal(I.E. SEGV or SIGILL) but a 'continue' in gdb will let
you trace the program.
