Thanks for the report!
That is a bug in bash's builtin printf function, not in the
one from sh-utils.
To use the version from the sh-utils package, you can invoke it like this:
$ `which printf` '%*s\n' a foo
/usr/bin/printf: a: expected a numeric value
foo
[Exit 1]
Here's what happens when I use bash's builtin printf:
$ echo $BASH_VERSION
2.05.0(1)-release
$ printf %*s a foo
bash: printf: a: invalid number
Segmentation fault
[Exit 139 (SIGSEGV)]
