Run the unit test lib/simpletest/testdmllib.php.
This results in errors similar to:
Fail: lib/simpletest/testdmllib.php / ? dmllib_test / ? test_backslashes_and_quotes / ?
Equal expectation fails at character 0 with [new entry] and [insert backslashes and quotes alone (even): "" ''
] at [/opt/local/www/m19/lib/simpletest/testdmllib.php line 348]
test_backslashes_and_quotes() is getting cached data instead of the record inserted immediately before the select, and so the test fails.
