No backtrace?  Did the testing Emacs segfault or something?

I've tried running "make check" myself now on Macos, and I see no
failures.

Indeed, there is a crash (SIGABRT).  Emacs exits with this output:

    Abort trap: 6

Running the tests interactively gives me the following output in the ert buffer:

Selector: t

...FF

F multi-test-sqlite-busy
    (error "near \"on\": syntax error")

F multi-test-sqlite-simple
    (error "near \"on\": syntax error")

If I try to get the ELisp backtrace from ert with "b", Emacs crashes
with the below rather unhelpful backtrace. Any ideas for how to debug
further from here are welcome.

I'm almost completely blank on running the debugger on Macos, but Gerd
is an expert here -- Gerd, any advice?

That's how quickly you get a bad reputation :-).

> -- Gerd, any advice?

It's to a degree similar to GDB.  I'm using the cheat sheet from
https://lldb.llvm.org/use/map.html if in doubt.  That's how experts do.

cd src
lldb --local-lldbinit emacs

You should see "Emacs support has been loaded".  If not, you can load it
later with

command script import ../etc/emacs_lldb.py

To start Emacs

run <args...>

where <args...> are command-line options for Emacs.  When back in lldb
because of the signal, use bt, up, down, and p as you would in GDB.
With emacs_lldb.py loaded, you can also use xbacktrace and xdebug_print.

It's in etc/DEBUG, isn't it?

Unfortunately, I can no longer reproduce this after upgrading to macOS
12.6.1.  I hope that someone in a position to reproduce this issue
will report it again if it has not already been solved.  Closing this
bug for now.
