I could confirm my initial suspicion: it's a *printf() library issue. The
FreeBSD CVS log tells the tale:
http://www.de.freebsd.org/cgi/cvsweb.cgi/src/lib/libc/stdio/vfprintf.c
The next FreeBSD subrelease (4.8?) should have this fixed. OpenBSD is not
fixed. NetBSD and Darwin seem to have temporarily hidden their cvsweb in
shame, but I would assume it's the same issue. Not sure what HP-UX is
doing about it.
