Description Tony Finch 2000-11-09 22:10:01 UTC 
I tried to add another partition to the above configuration and I gave it the
letter 'i'. When I quit the editor, disklabel died from a segmentation fault
on line 841 of disklabel.c because the variable lp had been corrupted. I worked
out that this occurred in getasciilabel() because of an off-by-one error.

While I am here I note that disklabel handles editing the file in a way similar
to the way that crontab used to, until a vulnerability was found recently. I
don't know if it could cause problems, though.
