Follow-up Comment #1:

Yup, something is definitely wrong here, both with the code and with the test
I wrote, because that should have flagged this kind of misbehavior.

I'll dig into it.

Also, it doesn't matter much, but I would single-quote the argument to
_printf_(1).  You have triple backslashes before the register interpolation,
so I would expect printf to interpret that as a backslash followed by a
newline.

However (1) we should *still* be getting at least "systat=" on the standard
error stream, and (2) I'm not sure what semantics the shell applies to
backslashes in a double-, as opposed to single-quoted argument, and this might
vary depending on the shell.

Thanks for the report--I suspect you caught a humdinger here.
