I've been using Cygwin and Cygwin Emacs for a long time on Windows 11. I have
to reinstall it every couple of years. I just reinstalled Cygwin yesterday,
and after having to remember a bunch of things, I finally got my Emacs window
again. However, the main thing I use it for is giving me a new problem. I
have a wrapper function that creates a new buffer and runs "(shell)". This has
literally worked fine for decades. Today, it worked fine for the first shell.
The package allows me to manage multiple shell buffers. When I tried to create
the second shell buffer, it said this:
bash: cannot set terminal process group (-1): Inappropriate ioctl for device
bash: no job control in this shell
If I just kill this buffer at this point, I can safely interact with the first
shell buffer. However, if I execute any command, it seems to execute it in an
infinite loop, and if I then kill the buffer, the Emacs process is completely
hung, and I have to kill the entire process.
This is using Emacs v29.4.
I've already reported this to the help-gnu-emacs list, and they said I should
ask here instead.
