handle_fault error2, how to find what is causing it?

I have a program which I daily use, it is website revision system and
customer relationship management in CLISP.

Now, it was just working. No problems.

Today, no problems, and no day before.

Suddenly I am getting errors:

*** - handle_fault error2 ! address = 0xcccedd220 not in [0x334eda000,0x335768040) !
SIGSEGV cannot be cured. Fault address = 0xcccedd220.
GC count: 155

Currently in use: 14306760 bytes.
Free space: 3292664 bytes.
Segmentation fault

where the fault address is changing.

I can see from dmesg:
[ 1566.837844] lisp.run[1046]: segfault at cccbec220 ip 000000000042371d sp 00007ffd3c6fa9f0 error 6 in lisp.run[400000+205000]

Can it be my computer is not good?

Or if not computer, how do I search for error?
