The info page does:
`%S'
This is an alias for `%ls' which is supported for compatibility
with the Unix standard.
And later:
`l'
Specifies that the argument is a `long int' or `unsigned long
int', as appropriate. Two `l' characters is like the `L'
modifier, below.
If used with `%c' or `%s' the corresponding parameter is
considered as a wide character or wide character string
respectively. This use of `l' was introduced in Amendment 1 to
ISO C90.
So %S is looking for a null-terminated string of wchar_t. Since the input
string isn't wchar_t, it crashes on wcslen().
