This doesn't cause anything other than the expected to happen (ie,
it returns "%.d") using 5.1.2 or 5.1.4 under Ubuntu Linux, so I suspect
it may be your OS's C library treating such strings differently than
glibc.
If this is a widespread issue (which OS are you on) then it may be
worth investigating adding a layer of checking of the format string to
Lua's wrapper for it.
