So if you provide a string literal, there's no warning because it's
assumed you're not going to hard-code stray '%' characters in it. If
you provide arguments after the string (whether literal or not),
it's assumed you've made sure the string really is a format string.
If you provide a non-ilteral string and no arguments, there's a fair
chance that you've forgotten that some potential string values will
blow up, hence the warning.
It's not a bug in most cases mentioned here:
If you have no arguments, you should be using puts() instead of printf
() and fputs() instead of fprintf() (or in the case of
+stringWithFormat:, use +stringWithString:, or just copy or retain the
string, or use it directly).
In the case of NSLog(), use a constant format string (at least
@"%@") instead of passing a string.
It seems the only case it's really a bug is NSLog(), because there's
no variant of NSLog() without a format string, and as someone else
posted here, it's apparently an undesired interaction with -fno-
constant-strings, so file a bug.
