printf(1) of the shell-utils stuffs has a bug that appears when a
conversion code fails to convert a number argument with '*' and then
attempts to print a string anyway.
Examples:
printf %*s a foo
printf %.*s text asdf
Both of these will typically print garbage to the terminal, sometimes
munging things up to require a 'reset'. They will occasionally result in
the death of their parent shell.
Thanks
