[lldb-dev] What's the right way to use ThreadPlanCallFunction

[Keno Fischer]

Hey everyone, I'm having some trouble using ThreadPlanCallFunction, I tried
the following, but for some reason the reference that the thread stores
in m_completed_plan_stack does not increment the use count of the shared
ptr.
I have tried debugging this, but gotten nowhere, so I figured I must be
missing something. Does this code look ok? (Ignore the debug print
statements, though for completeness, the output is

        if (!ctx.HasThreadScope())
        {
            error_stream.Printf("ClangUserExpression::Execute called with
no thread selected.");
            return lldb::eExpressionSetupError;
        }

        lldb_private::EvaluateExpressionOptions options;
        llvm::ArrayRef <lldb::addr_t> args;

        lldb::ThreadPlanSP call_plan_sp(new
lldb_private::ThreadPlanCallFunction(ctx.GetThreadRef(), address,
$(ClangASTType(C,rt)), args, options));
        std::cout << call_plan_sp.use_count() << "\n";

        if (!call_plan_sp || !call_plan_sp->ValidatePlan (&error_stream))
            return lldb::eExpressionSetupError;

        std::cout << call_plan_sp.use_count() << "\n";

        lldb::ExpressionResults execution_result =
ctx.GetProcessRef().RunThreadPlan (ctx,

       call_plan_sp,

       options,

       error_stream);

        std::cout << ctx.GetThreadRef().m_completed_plan_stack[1].get() <<
"\n";
        std::cout <<
ctx.GetThreadRef().m_completed_plan_stack[1].use_count() << "\n";

        std::cout << call_plan_sp.get() << "\n";
        std::cout << call_plan_sp.use_count() << "\n";

        return lldb::eExpressionCompleted;
