FYI, this is because glibc's snprintf is a thin
wrapper around vasnprintf, and as its name implies,
that latter may well allocate heap storage.
However, "fixing" this problem in glibc would mean adapting
or cloning the 5000+ lines of vasnprintf.c (already littered
with well-nested #ifdefs), and neither prospect is inviting.
