I know that PPC is not affected.Just tried this on a dual PPro: % cat > try.c void main () { * (unsigned int *) 0 = 0; } % cc -o try try.c % ./try Segmentation fault % ldd core % dmesg | tail -1 perfmon: v0.4 (19990127) Richard Gooch (rgooch () atnf csiro au), 2 counters Nope, doesn't cause a reboot, panic, Oops or any problems here. Running as root makes no difference. Regards, Richard....
