If the process exceeds the limit, the kernel sends it a SIGXCPU signal, and then, if the process doesn't terminate, a SIGKILL signal (see Chapter 11).

You can catch any signal except SIGKILL, SIGCONT and SIGSTOP. Thus you can catch SIGSEGV, but if you decide then not to exit, the behavior will be unpredictable.
