Could you find out the contents of the buffer it's trying to read?
A bisect would be great too, of course. Is this a recent problem?

I'm trying to debug window.c. But I have no idea if that's what
‘json-read-string’ tries to read.
> A bisect would be great too, of course. Is this a recent problem?
I've seen it yesterday for the first time. I can't reproduce it
reliably but it can hit any time, often when next stepping with gdb.
Also I wasn't able to reproduce it on Debian so far. Bisecting on
Windows is a pain here.

Ah, so the problem is likely not in json.el? I figured it was.

How would I know what what ‘json-read-string’ tries to read at that
moment? Am I supposed to instrument it? Maybe
(unless (char-equal (json-peek) ?\")
(signal 'json-string-format (list "doesn't start with `\"'!")))
should report the current buffer and its value of point.
Anyway, if I understand the backtrace correctly, the current buffer
should have been "*breakpoints of emacs.exe*".

...you can add a (debug) call before (signal ...). And when the debugger
hits, press `e' and evaluate (buffer-string) and (point).
Seeing the value of buffer-string might be sufficient if json-read is
being called in a wrong buffer.

I wouldn't mind if it did. Though that would need to be done in all such
places.
But for the purposes of debugging, you can modify just that function's
definition to report what's required.

I'm not sure what that implies. Does it have JSON content?

It is reading from the buffer where we insert the GDB response, you
can see that as a string in the backtrace you posted.
Martin, can you try coming up with a reproducible recipe? It's hard
to debug a problem that one cannot reproduce. (I tried to start
gdb-mi and step a few steps through the Emacs code, but never saw the
problem.)

Can you switch to that buffer and look what's at point? And while at
that, post here the full contents of that buffer?

But what is the use of the above signal when it doesn't tell me where to
find the source of the problem?

Which places?

I do so already. Now it stopped complaining. Yet another Heisenbug.

What is JSON content?

You mean *breakpoints of emacs.exe*? This is the only buffer I see
mentioned in the backtrace.

I would like to. Yesterday I wasn't able to get around it. Since
today's morning I'm not able to reproduce it.

When I manage to reproduce it, I will post the contents of the buffer.

Yes, probably.

json.el is written in Lisp, so there are many ways you can get the
needed information. All of them are relatively easy, IMHO.

Every place in json.el that contains "(signal 'json-", probably. We

String in JSON format.
Basically, the question is whether we're calling json-read in a wrong
buffer, or if the buffer is right but contains unparseable content, or
if we fail to parse valid JSON.

Definitely not the first alternative. Either the 2nd or the 3rd.

It just happened again while debugging xdisp.c. The buffer is called
*partial-output-emacs.exe* (with a leading space) it contains 2295
characters and its position of point was 2. The contents of that buffer
are hopefully in the attached file partial-output-emacs.txt (for reasons
that elude me I was not able to inline them with Thunderbird).
The contents of *backtrace* are:
Debugger entered--Lisp error: (json-string-format "doesn't start with `\"'!")
signal(json-string-format ("doesn't start with `\"'!"))
(if (char-equal (json-peek) 34) nil (message "%s ... %s" (current-buffer) (point)) (signal (quote json-string-format) (list "doesn't start with `\"'!")))

There are null bytes after `{"width":"4","alignment":"-1",'. So it's
a small wonder that json.el chokes. IOW, this is not a problem with
either json.el not gdb-mi.el, but a much more fundamental problem with
low-level Emacs functions that insert text into a buffer.
When did you last update from the emacs-25 branch?

I see. Thunderbird choked as well, but I did not investigate.

Maybe related to the loaddefs.el case. That one stroke again here a few
days ago on my Debian machine.

This happend on my patched version of master/trunk. So if anything we
could conclude that we may have been injecting null bytes already before
cutting the release branch.

I suspect the undo changes, and the fact that they caused running Lisp
and could trigger GC in the middle of fiddling with the buffer's gap.
They were committed to master before the branch was cut. That's why I
asked about your update: that hole was plugged 2 days ago on the
emacs-25 branch.

This also means that some bug reports we got over the past weeks are
unreliable. And we might get more of them for master/trunk if we don't
merge the changes back soon.

Assuming my suspicion is right, yes.

Apparently I didn't manage to do that in the past two years so I'm
closing this bug.
