            Bug ID: 21620
           Summary: SB API GetValueDidChange() returns false although
                    value did change, on FreeBSD
           Product: lldb
           Version: unspecified
          Hardware: PC
                OS: FreeBSD
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs
          Assignee: lldb-dev at cs.uiuc.edu

FAIL: test_with_dwarf_and_process_launch_api
(TestValueVarUpdate.HelloWorldTestCase)
   Test SBValue::GetValueDidChange

    self.assertTrue(i.GetValueDidChange(), "GetValueDidChange() is
saying a lie")
AssertionError: False is not True : GetValueDidChange() is saying a lie
Config=x86_64-/usr/bin/clang

The two assertions here are:

        self.assertTrue(i_val != i.GetValueAsUnsigned(0), "GetValue()
is saying a lie")
        self.assertTrue(i.GetValueDidChange(), "GetValueDidChange() is
saying a lie")

which is a bit odd: GetValueAsUnsigned shows that the variable's value
has been updated, but that's not reflected in GetValueDidChange. It
fails both with parallel tests (8 CPUs) and without parallelism.
However, if I invoke this test in isolation (though python dotest.py
-f ...) it passes.
