> > What does "Bus error" mean? "The memory bus reference was out of allowable address space" In general, since page 0 is not mapped, it will typically mean that you have dereferenced a null pointer. Probably by relying on the historical behaviour of strcat/strcpy/etc.. In all cases, it's a pointer error of one kind or another, though it could just as easily result from stack or array bounds based corruption of a pointer value, as it could from some error with the pointer usage itself.
