If you only want to know whether a function was called, how about
adding a variable to which those calls (where you wanted to add
printf's) will add indications each time the function is called?
Like, for example, a char [] array to which those places would add
some simple text?

But I admit that I have only a vague idea of what you are trying to
establish, so perhaps if I understood it better, I could suggest
better methods of logging this information without incurring
Shrödinger-cat like effects.
