[Mondo-devel] buffer overflow?

[Morgan R. <ms...@re...>]

Hello Folks,

I'm getting a "buffer overflow" failure (output copied below, log
attached) when executing:

sudo /usr/sbin/mondoarchive -Oc 4 -D -I "/home/morgan /etc" -N -d
/dev/hdc -m -s 700m -9 -F -e -T /tmp -S /tmp -W -E\
>  "/home/morgan/Public\
>   /home/morgan/AudioVisualFiles/Stills\
>   /home/morgan/.BasiliskII/Volumes\
>   /home/morgan/.beagle\
>   /home/morgan/.Trash\
>   /home/morgan/.thunderbird/p0axlukx.default/News\
>   /home/morgan/.thunderbird/p0axlukx.default/ImapMail\
>   /home/morgan/.thunderbird/p0axlukx.default/Mail/Local
Folders/Archive.sbd"

I don't get the same failure when I execute:

sudo /usr/sbin/mondoarchive -Oc 8 -Vc 24 -I "/home/morgan /etc" -N -d
/dev/hdc -g -m -s 700m -9 -F -e -S /tmp -T /tmp -E\
 "/home/morgan/Public\
  /home/morgan/AudioVisualFiles/Stills\
  /home/morgan/.BasiliskII/Volumes\
  /home/morgan/.beagle"

Any ideas would be much appreciated - shall I file a bug for this?
Regards,
Morgan.
