Thanks for reporting this.  It occurs for me in macOS in every version
of Emacs starting from 24.3, but not in version 23.4.  There must have
been a regression in between those two versions.

I can’t reproduce in either 26 or the master branch. Strange.

Odd.

On this box, the behavior traces back to the following commit.

  commit 2b0a91e78f83fb446cc38efb99399e83ad2cded3
  Author: Stefan Monnier <monnier <at> iro.umontreal.ca>
  Date:   Mon Apr 12 22:07:48 2010 -0400

      Try to solve the problem of spurious EOF chars in long lines of text
      sent to interactive subprocesses.
      * sysdep.c (child_setup_tty): Do not enable ICANON any more.
      (system_process_attributes): Remove unused var `ttotal'.
      * process.c (send_process): Don't bother breaking long line with EOF
      chars when talking to ttys any more.
      (wait_reading_process_output): Output a warning when called in such
      a way that it could block without being interruptible.

Hi there,

I just want to follow up on this bug since it has been around for a while. Although I cannot reproduce this bug with the steps described in the original bug report, it definitely exists and can be reproduced in a clearer way: https://emacs.stackexchange.com/questions/40603/process-input-seems-buggy-in-emacs-on-os-x
I personally encountered this in ESS inferior R buffer: https://github.com/emacs-ess/ESS/issues/1093

I have tested this under macOS Catalina and Big Sur with master branch Emacs and Yamamoto’s Emacs Mac Port. This bug can always be reproduced. I also tried on an m1 arm MacBook, and it is still there so it has nothing to do with architecture.

Hopefully this can help you identify the issue.

Oh I thought that was not conclusive, as the bug is not labeled as “confirmed” in the bug tracker. But anyways, I just wanted to add some extra info, useful or not, especially the testing on the m1 chip Mac. Thanks.
