Hi,
What are exactly your Linux distribution and version?
Does it crash on all queries, or on a certain query only?
Please try to run search.cgi from command line like this:
./search.cgi query words
where query words are the search words that make it crash.
Does it crash when started from command line?
If so, it would be nice to get a gdb backtrace.
Please do the following:
gdb search cgi
(gdb) run query words
(gdb) backtrace
Thanks.
