Actually, with the gnulib 'printf-posix' module, the probability of getting ENOMEM is higher than with the native printf() function: because lib/vfprintf.c accumulates the output into a string, whereas native printf() implementations internally operate on a stream and need less intermediate strings (possibly not even for padding).
