failed to even compile of course). In this case, any core dump file will
also be left available.
As a convenience for debugging, the tests use a start() function in which
they set the line number of the test, so you can stop in that function and
upon stepping out of it the debugger will be examining the specified test.
eg.
(gdb) break start if line == 42
(gdb) run
