To: 58850
From emacs -Q, execute the following:
(defun will-fail ()
(let ((db (sqlite-open (make-temp-file "will-fail"))))
(sqlite-execute db "SELECT foo FROM bar;")))
(will-fail)
Some combination of sqlite and getting errors that result in backtraces
seems to result in a problem.
Relevant information from the crash report:

Please try the latest master branch. Jonas installed changes there
that are related to sqlite error handling, and with today's master I
get a Lisp error with your recipe, not a crash:
Debugger entered--Lisp error: (sqlite-error ("SQL logic error" "no such table: bar" 1 1))

I've synced, rebuilt, verified Jonas's change is there, however the crash
still occurs.

Then please walk through the code with a debugger and tell us what
kind of object is being created as result of the error that Emacs
cannot print via prin1 because print_object barfs. I cannot do it
here because the problem doesn't happen on my system in the first
place.
The way to fix this is one of the following, whichever seems cleaner:
. repair the object before it gets to the printing routines,
preferably where it is created; or
. add some protection to routines in print.c to stop short of trying
to look too closely at invalid Lisp objects
Only debugging can tell which way is the best one here, but all things
being equal, I'd prefer the former.

Thanks for the advice.
Right now, I narrowed the problem down to the sqlite connection name
creation, since it is the printing of the sqlite object's name that causes
the crash.
The creation of the name is on sqlite.c line 269 (
https://git.savannah.gnu.org/cgit/emacs.git/tree/src/sqlite.c#n269). I can
make the crash go away by substituting that line with my own filename:
name = build_string("/tmp/test.db");
But I don't know what might be wrong with the line there as written. I'll
continue to investigate, but it's possible that someone with better
knowledge of the emacs internal idioms might spot the issue.

This is not at all clear from the backtrace you posted; see below.

That line just encodes the file name. I have hard time believing it
could cause a problem like this. What do you see in the value of
'name' after line 269 is executed?
For starters, please rebuild Emacs without optimizations and with
"--enable-checking=yes" at configure time, and then post a full
backtrace when running the recipe you posted. The original backtrace
you posted seems to come from an optimized build (so line numbers
don't tell the whole story), and includes multiple references to ERT
functions, from which I conclude it was not obtained by running the
recipe, but by running something much more complex.
Armed with the accurate backtrace, we might have a different picture
of what causes this problem.

which I find quite funny :-).
I haven't taken a close look, but I know that reading symbols goes so
great lengths of growing its buffer as needed. Maybe this is missing in
this case. Or something similar.

It does work for me, thank you for the fix! I don't think I really
understand what is going on here either (does anyone? is the length of the
path in the name the relevant thing here?), but if there's a solution that
works, then that's enough for me, thanks. I'll close this bug.

It was a classical stack-buffer overflow. The "name=..." part of the
printed representation of SQLite objects was printed to a fixed-size
buffer on the processor stack. With a long enough name, this overwrites
other stuff on the stack, like the return address, and boom. I fixed
this by not using a buffer al all, which is the way this is done
normally. There was actually no need for using the buffer in the first
place.
Thanks for the report, and the testing!
