I had for a while over clocked a 486/33 to 40mhz... when the fan on the cpu stopped working I would get sig6s during a compile... as soon as I put a fan back on the chip it all went away... also... it could be the motherboard... I had a vlb motherboard running an amd5x86/133 and it just wouldn't recoginize memory and the memory it would recognize was "bad" as far as freebsd was conserned... i.e. bad data was being writen to the disk...
