This one is interesting. It's come up before. Bash makes a copy of the
default locale (as returned by setlocale()) for its own purposes. Some
systems use a static buffer for that value; some systems, including glibc,
return allocated memory (even though the man page warns to not assume
anything about the returned string).
You're right about the two buffers for setlinebuf().
Thanks.
