--- Comment #1 from Mark Millard <markmi at dsl-only.net> ---
Hmm. Too much time at this I guess. . .

Reviewing again I do not find any __vfprintf paths that are without PRINT use
(i.e., io_print use). That should mean that io.uio.uio_iov->iov_base was
initialized but somehow changed.

I still have not replicated the problem with smaller/simpler code, only with
libc/stdio use.

I'll have to try some more after a break.
