More information about Lisp errors. I got a different Lisp error while 
leaving emacs-w32 -Q with TRAMP in the background. Output from the Lisp 
Debugger is shown below:

> Debugger entered--Lisp error: (error "Lisp nesting exceeds `max-lisp-eval-depth'")
>   seconds-to-time(0.5)
>   timer-relative-time((21130 28177 985108 200000) 0.5 0 nil)
>   timer-inc-time([t 21130 28177 985108 0.5 blink-cursor-timer-function nil nil 200000] 0.5 0)
>   timer-event-handler([t 21130 28177 985108 0.5 blink-cursor-timer-function nil nil 200000])

seconds-to-time is from time-date.el while the other three are from 
timer.el.


Cheers,

SDS

The steps I used to reproduce this are given below:
1) Run emacs-w32 -Q & in bash
2) M-x toggle-debug-on-error to enable the Emacs Lisp Debugger
3) C-x d to open a directory in Dired
4) Specify a remote directory
5) After the Dired buffer loads, open a file in the remote directory 
with <RET>
6) Minimize the Emacs window and wait

I'm not sure whether it's necessary to open the file to reproduce this 
error. I'll test this next.


Cheers,

SDS

Thanks for the clear instructions.  I can reproduce the Lisp errors, but 
so far I haven't seen an abort.  I've had one session running for about 
24 hours.

I'll look into the Lisp errors when I get a chance, but I wonder if 
there's something else going on (BLODA?) that's causing the abort on 
your system.  Do you have access to a Windows computer that doesn't have 
Symantec Endpoint Protection installed?

By the way, there have been some recent changes in the way emacs handles 
the blinking cursor.  One of the changes turns off the timer for the 
blinking cursor when emacs is idle, so it's possible that the problem is 
already fixed in the emacs trunk.  I'll look into this also.

emacs-w32/X11 24.3-7 aborts frequently

[SDS]

Thanks for the assistance Ken, I appreciate it. I was able to uninstall 
Symantec Endpoint Protection, so the only piece of software that I may 
have from the BLODA list is now NVIDIA Geforce. I took your advice about 
experimentation, and I discovered some more information.

It turns out that Emacs will abort regardless of whether it's X11 or 
w32, or even whether TRAMP is in use (I changed the subject title to 
reflect this). However, while emacs-w32 does display an abort dialog box 
when it aborts, emacs-X11 does not. The minimal sequence of steps to 
generate an abort in emacs-w32 is now the following:

1) Run "emacs-w32 -Q &" in bash.
2) Use "M-x toggle-debug-on-error" to enable the Emacs Lisp Debugger.
3) Minimize the Emacs window and wait.

If I do this for many Emacs sessions at a time (e.g. seven), then at 
least one usually aborts within a few hours.

It's also not a strict requirement that the session be minimized or 
idle. I had one session abort while typing in my password for a remote 
directory access using TRAMP. This happened about three minutes after 
starting that session.

I've collected a number of Emacs session logs, detailing Lisp errors and 
abort backtraces from GDB, but I'm not sure how useful it would be to 
you. To summarize, the Lisp errors were of the following types:

> Debugger entered--Lisp error: (wrong-type-argument characterp [nil 21130 37499 445325 0.5 blink-cursor-timer-function nil nil 100000])

There were also a few general errors such as:

For aborts, I only have backtraces for emacs-w32, since emacs-X11 didn't 
allow me to attach GDB before aborting. Most of those backtraces look 
like this:

The rest are a slight variation of this. There was one occasion where 
emacs-w32 just hanged, taking up 100% of a virtual CPU core, and I had 
to kill it from bash. This has also occasionally happened with the ssh 
process when I do a save-buffer using TRAMP, but I can usually use C-g 
to quit the command and recover from the hang. Repeated attempts to save 
hang as well, but I can rename/copy/delete the file in Dired. I can also 
usually write to the same file if I just restart Emacs. This may be more 
of an issue with the remote than Emacs, so I'm not as concerned with 
this as I am with the aborting.

If you want the full logs, I can clean them up and attach them. I can 
also get you more information from GDB if it helps.


Cheers,

SDS

Re: emacs-w32/X11 24.3-7 aborts frequently

[SDS]

I have some new information. I tried using

> export CYGWIN="error_start=gdb -nw %1 %2"

and I was able to catch an abort in emacs-w32 that gave no abort dialog 
box, similar to emacs-X11 aborts. The log from GDB is given below:

I'm afraid I still have no explanation (except possible BLODA) for the 
aborts that you're getting.  After about six days of experimentation on 
my system, here's what I see:

1. No aborts or crashes.

2. Lisp errors involving timers, similar to yours, but only on 64-bit 
Cygwin and only when using Tramp.

3. With a build from the emacs trunk, the Lisp errors are gone.

In a few days I'll have time to make a build from the trunk available to 
you in case you want to see if that solves your problem.

Thanks for all the trouble you're going through to assist me with this. 
I actually had one more application from the BLODA, specifically Windows 
Defender. I had turned it off in the settings page, but I decided to go 
a step further and prevent the associated service from automatically 
starting. So far, I haven't seen an abort yet from Emacs, which is a 
good sign.

There's one other issue I'm having with Emacs, but I'm going to make a 
new thread for it to keep the topics separate.


Cheers,

SDS

Re: emacs-w32/X11 24.3-7 aborts frequently

Unfortunately, stopping the Windows Defender service didn't solve the 
aborting issue. I still get aborts with the following GDB backtrace:

I'm not sure stopping the service is enough.  Did you actually turn off 
Windows Defender via the Control Panel?

Re: emacs-w32 24.3-7 aborts frequently using TRAMP

Ran another session of emacs-w32 -Q with TRAMP. Opened a Dired buffer

The new session ended with the following Lisp error:
> Memory exhausted--use C-x s then exit and restart Emacs

The same steps from the previous session were used during this session:
> 1) Run emacs-w32 -Q & in bash
> 2) M-x toggle-debug-on-error to enable the Emacs Lisp Debugger
> 3) C-x d to open a directory in Dired
> 4) Specify a remote directory
> 5) After the Dired buffer loads, open a file in the remote directory with <RET>
> 6) Minimize the Emacs window and wait


Cheers,

SDS
