I cannot reproduce this locally. 7 or 8 tests are failing on the FreeBSD buildbot http://lab.llvm.org:8011/builders/lldb-x86_64-freebsd due to a pexpect error like so:

======================================================================
ERROR: test_driver_batch_mode_with_dwarf (TestBatchMode.DriverBatchModeTest)
   Test that the lldb driver's batch mode works correctly.
