Thanks Alex. That, ashamedly, I should have figured out!!! :-)
Actually, no. Really the compiler should have figured it out, but ...
Quite right. C compilers are really lazy. It goes back to developing
compilers to work on machines with 8K of RAM (or something like
that!). Just remember that in C, Michael, you are dealing with a
very arcane and archaic language. (Objective-C is the best flavour
of it though, even though it is very preprocessorish).
They are only as lazy as you allow them to be. In Objective-C,
avoiding the (id) type will generally lead to a relatively type safe
compilation experience.
In this particular situation, the compiler is currently unable to
typecheck the arguments to NSLog(). However, the compiler does a fine
job with fprintf()/sprintf()/printf(), etc...
There is some subtlety to supporting NSLog() validation, which is why
it isn't validated yet.
It is tracked in <rdar://problem/5195437>.
