>Description:
crontab segfaults when you try to add a new entry containing a '0' in the
monthfield. Here's a stacktrace from the dead process:
#0 0x804b9e9 in env_free ()
#1 0x804a8c4 in free_entry ()
#2 0x804b537 in load_entry ()
#3 0x804a6ca in replace_cmd () at /usr/src/usr.sbin/cron/crontab/crontab.c:551
#4 0x804a349 in edit_cmd () at /usr/src/usr.sbin/cron/crontab/crontab.c:454
#5 0x80497ad in main (argc=2, argv=0xbfbff7d8)
at /usr/src/usr.sbin/cron/crontab/crontab.c:117
#6 0x804960d in _start ()
>How-To-Repeat:
crontab -e
and add a line like so:
1 1 1 0 1 touch /tmp/blah
crontab will segfault and the new entry will not be added to the users crontab
