Hello,
The current version of dialog(1) under 10.3-RELEASE is very buggy, IMHO.
For instance, the next example has taken from "man pv":
(tar cf - . \
| pv -n -s $(du -sb . | awk '{print $1}') \
| gzip -9 > out.tgz) 2>&1 \
| dialog --gauge 'Progress' 7 70
dialog(1) will exit with core dump by default, because of this version
contains a regression as has been noted
in the changelog:
2013/09/28
+ fix a regression in gauge widget from 2013/09/28 changes;
dlg_reallocate_gauge() failed when no --title option was given
(report by Tritonas Insomnia).
The version of dialog(1) under 10.3 is older than this fix, of course.
Thanks!
P.S. I am not sure if this information is important, just to note for
mainteners.
