            Bug ID: 36048
           Summary: TestDataFormatterLibcxxVector.py and
                    TestDataFormatterLibcxxVector.py fail with -fmodules
           Product: lldb
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: All Bugs

These tests were not actually ever building with -fmodules because in
Makefile.rules, we strip out -fmodules for c++11 tests. If we stop doing that,
we see:

1: test_with_run_command_dsym
(TestDataFormatterLibcxxVector.LibcxxVectorDataFormatterTestCase)
   Test that that file and class static variables display correctly. ... ok
2: test_with_run_command_dwarf
(TestDataFormatterLibcxxVector.LibcxxVectorDataFormatterTestCase)
   Test that that file and class static variables display correctly. ... ok
3: test_with_run_command_gmodules
(TestDataFormatterLibcxxVector.LibcxxVectorDataFormatterTestCase)
   Test that that file and class static variables display correctly. ...
FAILURE

The symptoms are that the data formatters print the wrong summaries for the
vector/list containers.
