Strange bug (buffer overflow) happening only under cron

[Pedro Fortuny]

Mmh, I put uname -a into the cron job and it says:

core file size          (blocks, -c) 0
data seg size           (kbytes, -d) unlimited
file size               (blocks, -f) unlimited
max locked memory       (kbytes, -l) unlimited
max memory size         (kbytes, -m) unlimited
open files                      (-n) 2560
pipe size            (512 bytes, -p) 1
stack size              (kbytes, -s) 8192
cpu time               (seconds, -t) unlimited
max user processes              (-u) 266
virtual memory          (kbytes, -v) unlimited

which is the same (exactly) as the output when run from
the shell (bash, by the way, in both environments).

Thanks, anyway.

Pedro.
