You misinterpret me. the behaviour / output of *printf() for
incorrect arguments etc. depends on the specification of the API.
It may result in special output (like "<NULL>" for a null pointer
reference).
But we should always return an error for unrecoverable error
situations that prevented proper operation accourding to the spec,
like out-of-memory situations.

No. Whener we run into bugs or bad code, we should fix it. Ot at
least flag it, so it can be fixed later.
We shall never, never ever paper over known issues.
Best regards,
