getopt_long requires that the last record in the longopts array is filled with 0 as documented in getopt(3) (cronolog-getopt-long.patch,1.08 KB, patch)

Description Carlo Marcelo Arenas Belon 2008-01-06 08:21:08 UTC 
cronolog leaves the array of long options as used in cronolog.c and cronotest.c without the required 0 filled last record, therefore the use of an unknown long option will traverse the array and segfault as shown in the linked URL

amd64 (at least for me) seems easier to replicate the problem as can be seen by :

$ /usr/sbin/cronolog --unknown-longopt
Segmentation fault

the same problem is also present in the test framework cronotest.c which doesn't get installed
