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
Passed:  3
Failed:  2 (2 unexpected)
Skipped: 0
Total:   5/5

...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.

Thread 2 received signal SIGABRT, Aborted.
