Subject: Bug? Output not flushed?
Date: Fri, 15 Sep 2023 09:56:17 -0700	[thread overview]
Message-ID: <CAH+w=7YnQmbVqNKHmt6nthB-+1KdFYhXt2vfVu2_uHP6S5RxMg@mail.gmail.com> (raw)

Easily reproduced:

% { print XXX; return 0; } >| /tmp/newfile; print $(</tmp/newfile)
% print $(</tmp/newfile)
XXX

That is, when a return statement appears in a current-shell complex
list, the output is not flushed until the parser reaches the top level
again.  If the return statement is removed, all is well:

% { print YYY; } >| /tmp/newfile; print $(</tmp/newfile)
YYY
%

Any idea where to start looking for this?
