Signal 4 is "illegal instruction" (see <sys/signal.h>)

Signal 10 is "bus error"

If they happen sporadic (but not always) in a non-reproducable manner they
could be a sign of hardware problems. (Signal 11 aka "segmentation violation"
would be another candidate, especially on other architectures like i386).

Check temperature/cooling of your CPU/FPU. (In my experiences sporadic
hardware problems with CPUs, harddiscs, tranceivers ... are usually caused
by heat)

If your Mac has a case without much air circulation (e.g. LC/Performa) let
it run with open (or without) case to see if it happens again.

If your CPU (FPU) is socketed or on a daughter card you might want to reseat
it (pull it carefully(!) out and put it carefully(!) back in) - sometimes
this helps.

Check/reseat the RAMs, cache, whatever....
