--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The warning is documented to be done only for loops that don't have multiple
exits (because otherwise it would have too many false positives; when the loop
isn't guaranteed to loop 16 times, there might not be an UB).
As printf is a possible cancellation point, it isn't marked throw() in the C
headers, so if you compile with C++ and don't turn off exceptions, the result
is expected - there are EH edges out of the printf call that might terminate
the loop.
