r18995: - fix bug 4078
- talloc_free(talloc_autofree_context()); should not result in a SIGABORT on exit - add a test for this, but this test can also pass in the standalone build and samba3, as samba4 uses talloc_autofree_context() metze (This used to be commit 2be48c1b033dceb9517826054b8ea97df2c94472)
