bug#25119: Hard freeze when switching to indirect buffer

Subject: bug#25119: Hard freeze when switching to indirect buffer
Date: Mon, 5 Dec 2016 09:46:19 -0700

Hi,

I use `emacs -nw` intensively for code development, often with 50+ files open for weeks at a time, many of them with indirect buffers created by `clone-indirect-buffer. Every once in a while, emacs will hard-freeze (ignoring both ^Z and ^G^G^G) when I switch to one of these indirect buffers. I'm forced to kill it from another terminal. I attached a snippet of a screenshot showing the terminal state at the time of the freeze.

The end of this email contains the relevant output of report-emacs-bug, invoked from a fresh session (since I can't do it for the hung session):

Attaching to the hung process with gdb, I see:

Thread 1 "emacs" received signal SIGTTOU, Stopped (tty output).
0x00007f60bf9a8960 in __GI_tcsetattr (fd=..., optional_actions=..., termios_p=...) at ../sysdeps/unix/sysv/linux/tcsetattr.c:83
83      ../sysdeps/unix/sysv/linux/tcsetattr.c: No such file or directory.

(gdb) xbacktrace
"suspend-emacs" (0xc652c910)
"suspend-frame" (0xc652cac0)
"call-interactively" (0xc652cc80)
"command-execute" (0xc652cdd8)

The hung process consumes no CPU according to `top`, but if I attempt to continue execution, SIGTTOU is raised repeatedly; telling gdb to silently pass the signal through to emacs leaves gdb working 100% CPU and emacs working 40% CPU, so I suspect SIGTTOU is being raised continuously.

Sending SIGUSR2 from the command-line has no visible effect, other than to make gdb hang when attempting to continue execution after attaching to the process; killing gdb with SIGTREM leaves the error message:

Detaching from program: /usr/bin/emacs24-x, process 122941
Exception ignored in: <gdb.GdbOutputFile object at 0x7f30a0375588>
Traceback (most recent call last):
  File "/usr/share/gdb/python/gdb/__init__.py", line 43, in flush
    def flush(self):
KeyboardInterrupt

Sending SIGTERM to emacs has no effect.

I suspect the call to `suspend-emacs` is due to my unsuccessful ^Z attempt, so the real problem is likely above that point in the stack trace. Next time this happens I will use the techniques mentioned in /usr/share/emacs/24.5/etc/DEBUG to hopefully obtain more information, without the added confound of attempting ^Z or ^G^G^G first.

The full backtrace is given at the end of this message.

Thanks,
Ryan
