First off, I don't use printf or friends very often (I write small

snprintf), I use gcc which will type-check the parameters against the
format so that any mistakes are caught - although with any variable
parameter function, you've lost much of C's already limited type
checking. Thirdly, I occasionally have to cast the parameters
explicitly so that I can be sure there are no mistakes.

Doesn't that imply a whole new set of things to worry about?

I would not say so, no.

I've come a cropper using gcc for ARM by passing an integer to a sprintf
that was expecting float. Caused my system to reset and took quite a
long time to find.
