Re: lua crashing on unrecognized strings

[Peter Cawley <lua@...>]

os.date is a wrapping around the strftime function provided by the C
runtime. On windows, the Microsoft C runtime is typically used, so
you'll want to consult the MSDN reference on strftime rather than one
of the standard documents. Likewise, io.open wraps fopen, and if the
underlying C runtime explodes on invalid input, then so will Lua.
