Log Message:
tests/snprintb: fix out-of-bounds memory read (since 2024-02-16)
Before t_snprintb.c 1.20, the buffer size was required to be greater
than zero. Allowing the buffer size to be zero led to buf[-1] being
checked. On amd64, that byte happened to be 0, on i386 it didn't.
Fixes PR lib/57951.
